| CVE-2020-26312 | 2024-11-21 | N/A | 8.1 HIGH | ||
| Dotmesh is a git-like command-line interface for capturing, organizing and sharing application states. In versions 0.8.1 and prior, the unsafe handling of symbolic links in an unpacking routine may enable attackers to read and/or write to arbitrary locations outside the designated target folder. The routine `untarFile` attempts to guard against creating symbolic links that point outside the directory a tar archive is extracted to. However, a malicious tarball first linking `subdir/parent` to `..` (allowed, because `subdir/..` falls within the archive root) and then linking `subdir/parent/escapes` to `..` results in a symbolic link pointing to the tarball’s parent directory, contrary to the routine’s goals. This issue may lead to arbitrary file write (with same permissions as the program running the unpack operation) if the attacker can control the archive file. Additionally, if the attacker has read access to the unpacked files, they may be able to read arbitrary system files the parent process has permissions to read. As of time of publication, no patch for this issue is available. | |||||
| CVE-2020-25857 | 1 Realtek | 2 Rtl8195a, Rtl8195a Firmware | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| The function ClientEAPOLKeyRecvd() in the Realtek RTL8195A Wi-Fi Module prior to versions released in April 2020 (up to and excluding 2.08) does not validate the size parameter for an rtl_memcpy() operation, resulting in a stack buffer overflow which can be exploited for denial of service. An attacker can impersonate an Access Point and attack a vulnerable Wi-Fi client, by injecting a crafted packet into the WPA2 handshake. The attacker does not need to know the network's PSK. | |||||
| CVE-2020-25856 | 1 Realtek | 2 Rtl8195a, Rtl8195a Firmware | 2024-11-21 | 6.8 MEDIUM | 8.1 HIGH |
| The function DecWPA2KeyData() in the Realtek RTL8195A Wi-Fi Module prior to versions released in April 2020 (up to and excluding 2.08) does not validate the size parameter for an rtl_memcpy() operation, resulting in a stack buffer overflow which can be exploited for remote code execution or denial of service. An attacker can impersonate an Access Point and attack a vulnerable Wi-Fi client, by injecting a crafted packet into the WPA2 handshake. The attacker needs to know the network's PSK in order to exploit this. | |||||

An attacker can impersonate an Access Point and attack a vulnerable Wi-Fi client, by injecting a crafted packet into the WPA2 handshake. The attacker needs to know the network's PSK in order to exploit this. | |||||
| CVE-2020-25854 | 1 Realtek | 2 Rtl8195a, Rtl8195a Firmware | 2024-11-21 | 6.8 MEDIUM | 8.1 HIGH |
| The function DecWPA2KeyData() in the Realtek RTL8195A Wi-Fi Module prior to versions released in April 2020 (up to and excluding 2.08) does not validate the size parameter for an internal function, rt_arc4_crypt_veneer() or _AES_UnWRAP_veneer(), resulting in a stack buffer overflow which can be exploited for remote code execution or denial of service.

| CVE-2020-25693 | 2 Cimg, Fedoraproject | 2 Cimg, Fedora | 2024-11-21 | 5.8 MEDIUM | 8.1 HIGH |
| A flaw was found in CImg in versions prior to 2.9.3. Integer overflows leading to heap buffer overflows in load_pnm() can be triggered by a specially crafted input file processed by CImg, which can lead to an impact to application availability or data integrity. | |||||
| CVE-2020-25647 | 4 Fedoraproject, Gnu, Netapp and 1 more | 8 Fedora, Grub2, Ontap Select Deploy Administration Utility and 5 more | 2024-11-21 | 7.2 HIGH | 7.6 HIGH |
| A flaw was found in grub2 in versions prior to 2.06. During USB device initialization, descriptors are read with very little bounds checking and assumes the USB device is providing sane values. If properly exploited, an attacker could trigger memory corruption leading to arbitrary code execution allowing a bypass of the Secure Boot mechanism. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | |||||

| CVE-2020-24659 | 4 Canonical, Fedoraproject, Gnu and 1 more | 4 Ubuntu Linux, Fedora, Gnutls and 1 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in GnuTLS before 3.6.15. A server can trigger a NULL pointer dereference in a TLS 1.3 client if a no_renegotiation alert is sent with unexpected timing, and then an invalid second handshake occurs. The crash happens in the application's error handling path, where the gnutls_deinit function is called after detecting a handshake failure. | |||||
| CVE-2020-24658 | 1 Arm | 1 Arm Compiler | 2024-11-21 | 4.4 MEDIUM | 7.8 HIGH |
| Arm Compiler 5 through 5.06u6 has an error in a stack protection feature designed to help spot stack-based buffer overflows in local arrays. When this feature is enabled, a protected function writes a guard value to the stack prior to (above) any vulnerable arrays in the stack. The guard value is checked for corruption on function return; corruption leads to an error-handler call. In certain circumstances, the reference value that is compared against the guard value is itself also written to the stack (after any vulnerable arrays). The reference value is written to the stack when the function runs out of registers to use for other temporary data. If both the reference value and the guard value are written to the stack, then the stack protection will fail to spot corruption when both values are overwritten with the same value. For both the reference value and the guard value to be corrupted, there would need to be both a buffer overflow and a buffer underflow in the vulnerable arrays (or some other vulnerability that causes two separated stack entries to be corrupted). | |||||
