Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: posix-clock: The missing timespec64 check in pcclocksettime has been fixed. As Andrew pointed out, it makes sense that the PTP core checks the tvsec and tvnsec fields of the timespec64 structure before calling ptp-info-settime64...

Astra Linux – Vulnerability in util-linux

util-linux is a random collection of Linux utilities. Prior to version 2.41.4, a TOCTOU Time-of-Check-Time-of-Use vulnerability was identified in the SUID binary /usr/bin/mount from util-linux. The mount binary, when setting up loop devices, validates the source file path with user privileges via...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: BPF: Using rawspinlockt in ringbuf. The function bpfringbufreserve is invoked from a tracepoint, which disables preemption. Using spinlockt in this context can lead to a “sleep in atomic” warning in the RT variant. This issue is...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: riscv, bpf: Fixed potential NULL dereferencing. The bpfjitbinaryfree function requires a non-NULL argument. When the RISC-V BPF JIT fails to converge within NRJITITERATIONS steps, jitdata-header will be NULL, triggering a NULL...

Astra Linux – Vulnerabilities in Linux, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: um: time-travel: fix time corruption In the “basic” time-travel mode without =inf-cpu or =ext, we still encounter timer interrupts. These can occur at arbitrary times, for example, while inside the timerread function, which simpl...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net/tcpmd5: The comparison of MACs has been fixed to require constant time. To prevent timing attacks, MACs need to be compared in constant time. Use the appropriate helper functions for this purpose...

Astra Linux – Vulnerability in Chromium

The use of after-free in WebRTC in Google Chrome before version 147.0.7727.55 allowed a remote attacker to execute arbitrary code within a sandbox through a crafted HTML page. Chromium security severity: High...

Astra Linux – Vulnerability in NTP

In NTP versions prior to 4.2.8p14 and 4.3.x before 4.3.100, ntpd allows an off-path attacker to block unauthenticated synchronization via a server mode packet with a spoofed source IP address. This occurs because transmissions are rescheduled even when a packet lacks a valid origin timestamp...

Astra Linux – Vulnerability in liblivemedia

In Live Networks, Inc., liblivemedia version 20200625, there is a potential buffer overflow bug in the server’s handling of the RTSP “PLAY” command, especially when the command specifies seeking by absolute time...

Astra Linux – Vulnerability in Linux

A flaw was discovered in the way RTAS handled memory accesses in user space for kernel communication. In a guest system that is under lockdown usually due to Secure Boot, running on top of PowerVM or KVM hypervisors pseries platform, a root-like local user could exploit this flaw to further...

Astra Linux – Vulnerability in Jinja2

This issue affects the Jinja2 package versions starting from 0.0.0 and earlier than 2.11.3. The ReDoS vulnerability is primarily caused by the punctuationre regex operator and its use of multiple wildcards. The last wildcard is the most exploitable, as it is used to search for trailing punctuatio...

Astra Linux – Vulnerability in pcre2

A out-of-bounds read was discovered in PCRE before version 10.34, where the pattern \X was JIT-compiled and used to match specially crafted subjects in non-UTF mode. Applications that use PCRE to parse untrusted input may be vulnerable to this flaw, as it could allow an attacker to cause the...

Astra Linux – Vulnerability in Chromium

Inappropriate implementation in WebRTC in Google Chrome prior to 143.0.7499.41 allowed a remote attacker to perform arbitrary read/write via a crafted HTML page. Chromium security severity: Low...

Astra Linux – Vulnerability in NTP

In the file libntp/mstolfp.c, within the NTP version 4.2.8p15, there is a buffer overflow vulnerability when copying the trailing number. An attacker may be able to exploit this vulnerability against a client’s NTPQ process, but they cannot exploit it against ntpd...

Astra Linux – Vulnerability in Linux 5.10

Due to a vulnerability in the iouring subsystem, it is possible for kernel memory information to be leaked to the user process. timensinstall calls currentissinglethreaded to determine whether the current process is single-threaded. However, this call does not take into account iouring’s ioworker...

Astra Linux – Vulnerability in Chromium

The use of after-free in WebRTC in Google Chrome before version 109.0.5414.119 allowed a remote attacker to potentially exploit heap corruption through a crafted HTML page. Chromium security severity: High...

Astra Linux – Vulnerability in Heimdal

The fix for CVE-2022-3437 involved changing the memcmp function to run in constant time, as well as providing a workaround for a compiler bug by adding comparisons of the result with the value “!= 0” to the memcmp function. When these patches were backported to the heimdal-7.7.1 and heimdal-7.8.0...

Astra Linux – Vulnerability in Linux

The file arch/powerpc/kvm/book3srtas.c in the Linux kernel, as of version 5.13.5 on the PowerPC platform, allows KVM guest OS users to cause memory corruption in the host OS through rtasargs.nargs, also known as CID-f62f3c20647e...
