CVE-2021-3975 4 Canonical, Debian, Fedoraproject and 1 more 13 Ubuntu Linux, Debian Linux, Fedora and 10 more 2024-04-01 N/A 6.5 MEDIUM
A use-after-free flaw was found in libvirt. The qemuMonitorUnregister() function in qemuProcessHandleMonitorEOF is called using multiple threads without being adequately protected by a monitor lock. This flaw could be triggered by the virConnectGetAllDomainStats API when the guest is shutting down. An unprivileged client with a read-only connection could use this flaw to perform a denial of service attack by causing the libvirt daemon to crash.
CVE-2023-35936 2 Debian, Pandoc 2 Debian Linux, Pandoc 2024-03-31 N/A 5.0 MEDIUM
Pandoc is a Haskell library for converting from one markup format to another, and a command-line tool that uses this library. Starting in version 1.13 and prior to version 3.1.4, Pandoc is susceptible to an arbitrary file write vulnerability, which can be triggered by providing a specially crafted image element in the input when generating files using the `--extract-media` option or outputting to PDF format. This vulnerability allows an attacker to create or overwrite arbitrary files on the system ,depending on the privileges of the process running pandoc. It only affects systems that pass untrusted user input to pandoc and allow pandoc to be used to produce a PDF or with the `--extract-media` option. The fix is to unescape the percent-encoding prior to checking that the resource is not above the working directory, and prior to extracting the extension. Some code for checking that the path is below the working directory was flawed in a similar way and has also been fixed. Note that the `--sandbox` option, which only affects IO done by readers and writers themselves, does not block this vulnerability. The vulnerability is patched in pandoc 3.1.4. As a workaround, audit the pandoc command and disallow PDF output and the `--extract-media` option.
CVE-2022-41946 2 Debian, Postgresql 2 Debian Linux, Postgresql Jdbc Driver 2024-03-29 N/A 5.5 MEDIUM
pgjdbc is an open source postgresql JDBC Driver. In affected versions a prepared statement using either `PreparedStatement.setText(int, InputStream)` or `PreparedStatemet.setBytea(int, InputStream)` will create a temporary file if the InputStream is larger than 2k. This will create a temporary file which is readable by other users on Unix like systems, but not MacOS. On Unix like systems, the system's temporary directory is shared between all users on that system. Because of this, when files and directories are written into this directory they are, by default, readable by other users on that same system. This vulnerability does not allow other users to overwrite the contents of these directories or files. This is purely an information disclosure vulnerability. Because certain JDK file system APIs were only added in JDK 1.7, this this fix is dependent upon the version of the JDK you are using. Java 1.7 and higher users: this vulnerability is fixed in 4.5.0. Java 1.6 and lower users: no patch is available. If you are unable to patch, or are stuck running on Java 1.6, specifying the java.io.tmpdir system environment variable to a directory that is exclusively owned by the executing user will mitigate this vulnerability.
CVE-2018-8822 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2024-03-28 7.2 HIGH 7.8 HIGH
Incorrect buffer length handling in the ncp_read_kernel function in fs/ncpfs/ncplib_kernel.c in the Linux kernel through 4.15.11, and in drivers/staging/ncpfs/ncplib_kernel.c in the Linux kernel 4.16-rc through 4.16-rc6, could be exploited by malicious NCPFS servers to crash the kernel or execute code.
CVE-2013-4184 2 Data\, Debian 2 \, Debian Linux 2024-03-28 3.6 LOW 5.5 MEDIUM
Perl module Data::UUID from CPAN version 1.219 vulnerable to symlink attacks
CVE-2021-31566 5 Debian, Fedoraproject, Libarchive and 2 more 14 Debian Linux, Fedora, Libarchive and 11 more 2024-03-27 N/A 7.8 HIGH
An improper link resolution flaw can occur while extracting an archive leading to changing modes, times, access control lists, and flags of a file outside of the archive. An attacker may provide a malicious archive to a victim user, who would trigger this flaw when trying to extract the archive. A local attacker may use this flaw to gain more privileges in a system.
CVE-2022-36227 4 Debian, Fedoraproject, Libarchive and 1 more 4 Debian Linux, Fedora, Libarchive and 1 more 2024-03-27 N/A 9.8 CRITICAL
In libarchive before 3.6.2, the software does not check for an error after calling calloc function that can return with a NULL pointer if the function fails, which leads to a resultant NULL pointer dereference. NOTE: the discoverer cites this CWE-476 remark but third parties dispute the code-execution impact: "In rare circumstances, when NULL is equivalent to the 0x0 memory address and privileged code can access it, then writing or reading memory is possible, which may lead to code execution."
CVE-2020-8169 4 Debian, Haxx, Siemens and 1 more 6 Debian Linux, Curl, Simatic Tim 1531 Irc and 3 more 2024-03-27 5.0 MEDIUM 7.5 HIGH
curl 7.62.0 through 7.70.0 is vulnerable to an information disclosure vulnerability that can lead to a partial password being leaked over the network and to the DNS server(s).
CVE-2020-8177 5 Debian, Fujitsu, Haxx and 2 more 16 Debian Linux, M10-1, M10-1 Firmware and 13 more 2024-03-27 4.6 MEDIUM 7.8 HIGH
curl 7.20.0 through 7.70.0 is vulnerable to improper restriction of names for files and other resources that can lead too overwriting a local file when the -J flag is used.
CVE-2020-8231 5 Debian, Haxx, Oracle and 2 more 5 Debian Linux, Libcurl, Communications Cloud Native Core Policy and 2 more 2024-03-27 5.0 MEDIUM 7.5 HIGH
Due to use of a dangling pointer, libcurl 7.29.0 through 7.71.1 can use the wrong connection when sending data.
CVE-2020-8285 9 Apple, Debian, Fedoraproject and 6 more 30 Mac Os X, Macos, Debian Linux and 27 more 2024-03-27 5.0 MEDIUM 7.5 HIGH
curl 7.21.0 to and including 7.73.0 is vulnerable to uncontrolled recursion due to a stack overflow issue in FTP wildcard match parsing.
CVE-2020-8286 8 Apple, Debian, Fedoraproject and 5 more 20 Mac Os X, Macos, Debian Linux and 17 more 2024-03-27 5.0 MEDIUM 7.5 HIGH
curl 7.41.0 through 7.73.0 is vulnerable to an improper check for certificate revocation due to insufficient verification of the OCSP response.
CVE-2021-22876 8 Broadcom, Debian, Fedoraproject and 5 more 12 Fabric Operating System, Debian Linux, Fedora and 9 more 2024-03-27 5.0 MEDIUM 5.3 MEDIUM
curl 7.1.1 to and including 7.75.0 is vulnerable to an "Exposure of Private Personal Information to an Unauthorized Actor" by leaking credentials in the HTTP Referer: header. libcurl does not strip off user credentials from the URL when automatically populating the Referer: HTTP request header field in outgoing HTTP requests, and therefore risks leaking sensitive data to the server that is the target of the second HTTP request.
CVE-2021-22890 8 Broadcom, Debian, Fedoraproject and 5 more 11 Fabric Operating System, Debian Linux, Fedora and 8 more 2024-03-27 4.3 MEDIUM 3.7 LOW
curl 7.63.0 to and including 7.75.0 includes vulnerability that allows a malicious HTTPS proxy to MITM a connection due to bad handling of TLS 1.3 session tickets. When using a HTTPS proxy and TLS 1.3, libcurl can confuse session tickets arriving from the HTTPS proxy but work as if they arrived from the remote server and then wrongly "short-cut" the host handshake. When confusing the tickets, a HTTPS proxy can trick libcurl to use the wrong session ticket resume for the host and thereby circumvent the server TLS certificate check and make a MITM attack to be possible to perform unnoticed. Note that such a malicious HTTPS proxy needs to provide a certificate that curl will accept for the MITMed server for an attack to work - unless curl has been told to ignore the server certificate check.
CVE-2021-22898 6 Debian, Fedoraproject, Haxx and 3 more 12 Debian Linux, Fedora, Curl and 9 more 2024-03-27 2.6 LOW 3.1 LOW
curl 7.7 through 7.76.1 suffers from an information disclosure when the `-t` command line option, known as `CURLOPT_TELNETOPTIONS` in libcurl, is used to send variable=content pairs to TELNET servers. Due to a flaw in the option parser for sending NEW_ENV variables, libcurl could be made to pass on uninitialized data from a stack based buffer to the server, resulting in potentially revealing sensitive internal information to the server using a clear-text network protocol.
CVE-2021-22946 8 Apple, Debian, Fedoraproject and 5 more 37 Macos, Debian Linux, Fedora and 34 more 2024-03-27 5.0 MEDIUM 7.5 HIGH
A user can tell curl >= 7.20.0 and <= 7.78.0 to require a successful upgrade to TLS when speaking to an IMAP, POP3 or FTP server (`--ssl-reqd` on the command line or`CURLOPT_USE_SSL` set to `CURLUSESSL_CONTROL` or `CURLUSESSL_ALL` withlibcurl). This requirement could be bypassed if the server would return a properly crafted but perfectly legitimate response.This flaw would then make curl silently continue its operations **withoutTLS** contrary to the instructions and expectations, exposing possibly sensitive data in clear text over the network.
CVE-2021-22924 7 Debian, Fedoraproject, Haxx and 4 more 53 Debian Linux, Fedora, Libcurl and 50 more 2024-03-27 4.3 MEDIUM 3.7 LOW
libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse, if one of them matches the setup.Due to errors in the logic, the config matching function did not take 'issuercert' into account and it compared the involved paths *case insensitively*,which could lead to libcurl reusing wrong connections.File paths are, or can be, case sensitive on many systems but not all, and caneven vary depending on used file systems.The comparison also didn't include the 'issuer cert' which a transfer can setto qualify how to verify the server certificate.
CVE-2021-22945 8 Apple, Debian, Fedoraproject and 5 more 25 Macos, Debian Linux, Fedora and 22 more 2024-03-27 5.8 MEDIUM 9.1 CRITICAL
When sending data to an MQTT server, libcurl <= 7.73.0 and 7.78.0 could in some circumstances erroneously keep a pointer to an already freed memory area and both use that again in a subsequent call to send data and also free it *again*.
CVE-2021-22947 8 Apple, Debian, Fedoraproject and 5 more 34 Macos, Debian Linux, Fedora and 31 more 2024-03-27 4.3 MEDIUM 5.9 MEDIUM
When curl >= 7.20.0 and <= 7.78.0 connects to an IMAP or POP3 server to retrieve data using STARTTLS to upgrade to TLS security, the server can respond and send back multiple responses at once that curl caches. curl would then upgrade to TLS but not flush the in-queue of cached responses but instead continue using and trustingthe responses it got *before* the TLS handshake as if they were authenticated.Using this flaw, it allows a Man-In-The-Middle attacker to first inject the fake responses, then pass-through the TLS traffic from the legitimate server and trick curl into sending data back to the user thinking the attacker's injected data comes from the TLS-protected server.
CVE-2022-22576 5 Brocade, Debian, Haxx and 2 more 17 Fabric Operating System, Debian Linux, Curl and 14 more 2024-03-27 5.5 MEDIUM 8.1 HIGH
An improper authentication vulnerability exists in curl 7.33.0 to and including 7.82.0 which might allow reuse OAUTH2-authenticated connections without properly making sure that the connection was authenticated with the same credentials as set for this transfer. This affects SASL-enabled protocols: SMPTP(S), IMAP(S), POP3(S) and LDAP(S) (openldap only).
