CVE-2018-17158 1 Freebsd 1 Freebsd 2024-02-04 7.8 HIGH 7.5 HIGH
In FreeBSD before 11.2-STABLE(r340854) and 11.2-RELEASE-p5, an integer overflow error can occur when handling the client address length field in an NFSv4 request. Unprivileged remote users with access to the NFS server can crash the system by sending a specially crafted NFSv4 request.
CVE-2018-6924 1 Freebsd 1 Freebsd 2024-02-04 5.6 MEDIUM 7.1 HIGH
In FreeBSD before 11.1-STABLE, 11.2-RELEASE-p3, 11.1-RELEASE-p14, 10.4-STABLE, and 10.4-RELEASE-p12, insufficient validation in the ELF header parser could allow a malicious ELF binary to cause a kernel crash or disclose kernel memory.
CVE-2019-5596 1 Freebsd 1 Freebsd 2024-02-04 7.2 HIGH 8.8 HIGH
In FreeBSD 11.2-STABLE after r338618 and before r343786, 12.0-STABLE before r343781, and 12.0-RELEASE before 12.0-RELEASE-p3, a bug in the reference count implementation for UNIX domain sockets can cause a file structure to be incorrectly released potentially allowing a malicious local user to gain root privileges or escape from a jail.
CVE-2018-17154 1 Freebsd 1 Freebsd 2024-02-04 4.9 MEDIUM 5.5 MEDIUM
In FreeBSD before 11.2-STABLE(r338987), 11.2-RELEASE-p4, and 11.1-RELEASE-p15, due to insufficient memory checking in the freebsd4_getfsstat system call, a NULL pointer dereference can occur. Unprivileged authenticated local users may be able to cause a denial of service.
CVE-2018-17156 1 Freebsd 1 Freebsd 2024-02-04 4.3 MEDIUM 5.9 MEDIUM
In FreeBSD before 11.2-STABLE(r340268) and 11.2-RELEASE-p5, due to incorrectly accounting for padding on 64-bit platforms, a buffer underwrite could occur when constructing an ICMP reply packet when using a non-standard value for the net.inet.icmp.quotelen sysctl.
CVE-2018-17159 1 Freebsd 1 Freebsd 2024-02-04 7.8 HIGH 7.5 HIGH
In FreeBSD before 11.2-STABLE(r340854) and 11.2-RELEASE-p5, the NFS server lacks a bounds check in the READDIRPLUS NFS request. Unprivileged remote users with access to the NFS server can cause a resource exhaustion by forcing the server to allocate an arbitrarily large memory allocation.
CVE-2017-1084 1 Freebsd 1 Freebsd 2024-02-04 7.8 HIGH 7.5 HIGH
In FreeBSD before 11.2-RELEASE, multiple issues with the implementation of the stack guard-page reduce the protections afforded by the guard-page. This results in the possibility a poorly written process could be cause a stack overflow.
CVE-2018-6922 1 Freebsd 1 Freebsd 2024-02-04 5.0 MEDIUM 5.3 MEDIUM
One of the data structures that holds TCP segments in all versions of FreeBSD prior to 11.2-RELEASE-p1, 11.1-RELEASE-p12, and 10.4-RELEASE-p10 uses an inefficient algorithm to reassemble the data. This causes the CPU time spent on segment processing to grow linearly with the number of segments in the reassembly queue. An attacker who has the ability to send TCP traffic to a victim system can degrade the victim system's network performance and/or consume excessive CPU by exploiting the inefficiency of TCP reassembly handling, with relatively small bandwidth cost.
CVE-2016-6559 1 Freebsd 1 Freebsd 2024-02-04 7.5 HIGH 9.8 CRITICAL
Improper bounds checking of the obuf variable in the link_ntoa() function in linkaddr.c of the BSD libc library may allow an attacker to read or write from memory. The full impact and severity depends on the method of exploit and how the library is used by applications. According to analysis by FreeBSD developers, it is very unlikely that applications exist that utilize link_ntoa() in an exploitable manner, and the CERT/CC is not aware of any proof of concept. A blog post describes the functionality of link_ntoa() and points out that none of the base utilities use this function in an exploitable manner. For more information, please see FreeBSD Security Advisory SA-16:37.
CVE-2017-1083 1 Freebsd 1 Freebsd 2024-02-04 7.8 HIGH 7.5 HIGH
In FreeBSD before 11.2-RELEASE, a stack guard-page is available but is disabled by default. This results in the possibility a poorly written process could be cause a stack overflow.
CVE-2019-5595 1 Freebsd 1 Freebsd 2024-02-04 2.1 LOW 5.5 MEDIUM
In FreeBSD before 11.2-STABLE(r343782), 11.2-RELEASE-p9, 12.0-STABLE(r343781), and 12.0-RELEASE-p3, kernel callee-save registers are not properly sanitized before return from system calls, potentially allowing some kernel data used in the system call to be exposed.
CVE-2018-17157 1 Freebsd 1 Freebsd 2024-02-04 10.0 HIGH 9.8 CRITICAL
In FreeBSD before 11.2-STABLE(r340854) and 11.2-RELEASE-p5, an integer overflow error when handling opcodes can cause memory corruption by sending a specially crafted NFSv4 request. Unprivileged remote users with access to the NFS server may be able to execute arbitrary code.
CVE-2016-9042 4 Freebsd, Hpe, Ntp and 1 more 5 Freebsd, Hpux-ntp, Ntp and 2 more 2024-02-04 4.3 MEDIUM 5.9 MEDIUM
An exploitable denial of service vulnerability exists in the origin timestamp check functionality of ntpd 4.2.8p9. A specially crafted unauthenticated network packet can be used to reset the expected origin timestamp for target peers. Legitimate replies from targeted peers will fail the origin timestamp check (TEST2) causing the reply to be dropped and creating a denial of service condition.
CVE-2018-6249 5 Freebsd, Linux, Microsoft and 2 more 5 Freebsd, Linux Kernel, Windows and 2 more 2024-02-04 7.2 HIGH 8.8 HIGH
NVIDIA GPU Display Driver contains a vulnerability in kernel mode layer handler where a NULL pointer dereference may lead to denial of service or potential escalation of privileges.
CVE-2018-6253 5 Freebsd, Linux, Microsoft and 2 more 5 Freebsd, Linux Kernel, Windows and 2 more 2024-02-04 4.9 MEDIUM 5.5 MEDIUM
NVIDIA GPU Display Driver contains a vulnerability in the DirectX and OpenGL Usermode drivers where a specially crafted pixel shader can cause infinite recursion leading to denial of service.
CVE-2018-8897 8 Apple, Canonical, Citrix and 5 more 11 Mac Os X, Ubuntu Linux, Xenserver and 8 more 2024-02-04 7.2 HIGH 7.8 HIGH
A statement in the System Programming Guide of the Intel 64 and IA-32 Architectures Software Developer's Manual (SDM) was mishandled in the development of some or all operating-system kernels, resulting in unexpected behavior for #DB exceptions that are deferred by MOV SS or POP SS, as demonstrated by (for example) privilege escalation in Windows, macOS, some Xen configurations, or FreeBSD, or a Linux kernel crash. The MOV to SS and POP SS instructions inhibit interrupts (including NMIs), data breakpoints, and single step trap exceptions until the instruction boundary following the next instruction (SDM Vol. 3A; section 6.8.3). (The inhibited data breakpoints are those on memory accessed by the MOV to SS or POP to SS instruction itself.) Note that debug exceptions are not inhibited by the interrupt enable (EFLAGS.IF) system flag (SDM Vol. 3A; section 2.3). If the instruction following the MOV to SS or POP to SS instruction is an instruction like SYSCALL, SYSENTER, INT 3, etc. that transfers control to the operating system at CPL < 3, the debug exception is delivered after the transfer to CPL < 3 is complete. OS kernels may not expect this order of events and may therefore experience unexpected behavior when it occurs.
CVE-2015-1416 1 Freebsd 1 Freebsd 2024-02-04 9.3 HIGH 7.8 HIGH
Larry Wall's patch; patch in FreeBSD 10.2-RC1 before 10.2-RC1-p1, 10.2 before 10.2-BETA2-p2, and 10.1 before 10.1-RELEASE-p16; Bitrig; GNU patch before 2.2.5; and possibly other patch variants allow remote attackers to execute arbitrary shell commands via a crafted patch file.
CVE-2018-7183 4 Canonical, Freebsd, Netapp and 1 more 4 Ubuntu Linux, Freebsd, Element Software and 1 more 2024-02-04 7.5 HIGH 9.8 CRITICAL
Buffer overflow in the decodearr function in ntpq in ntp 4.2.8p6 through 4.2.8p10 allows remote attackers to execute arbitrary code by leveraging an ntpq query and sending a response with a crafted array.
CVE-2018-6921 1 Freebsd 1 Freebsd 2024-02-04 2.1 LOW 5.5 MEDIUM
In FreeBSD before 11.1-STABLE(r332066) and 11.1-RELEASE-p10, due to insufficient initialization of memory copied to userland in the network subsystem, small amounts of kernel memory may be disclosed to userland processes. Unprivileged authenticated local users may be able to access small amounts of privileged kernel data.
CVE-2018-3665 6 Canonical, Citrix, Debian and 3 more 14 Ubuntu Linux, Xenserver, Debian Linux and 11 more 2024-02-04 4.7 MEDIUM 5.6 MEDIUM
System software utilizing Lazy FP state restore technique on systems using Intel Core-based microprocessors may potentially allow a local process to infer data from another process through a speculative execution side channel.
