Astra Linux – Vulnerability in libxstream-java

XStream is a simple library for serializing objects to XML and back again. In affected versions, this vulnerability may allow a remote attacker to allocate 100% of the CPU resources on the target system, depending on the type of CPU or through parallel execution of such a payload. This results in...

In the Linux kernel, the following vulnerability has been resolved: posix-cpu-timers: This issue prevents UAF Use-after-Allocation caused by a race condition involving non-leader exec. Wongi and Jungwoo identified and reported a race condition related to exec, which can lead to UAF. The detailed...

Astra Linux – Vulnerability in freeipa

A flaw was discovered in all IPA versions ranging from 4.x.x to 4.8.0. When sending a very long password = 1,000,000 characters to the server, the password hashing process could exhaust memory and CPU resources, resulting in a denial of service and making the website unresponsive. The greatest...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: bpf, cpumap: Handle skb as well when cleaning up ptrring. The following warning was reported when running xdpredirectcpu with both skbmode and stressmode enabled: ------------ Cut here ------------ Incorrect XDP memory type...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: cpufreq: intelpstate: A issue related to the object lifecycle was fixed in updateqosrequest. The cpufreqcpuput call in updateqosrequest occurs too early. This is because updateqosrequest subsequently calls freqqosupdaterequest,...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: MIPS: cpuinfo: Fixed a warning for CONFIGCPUMASKOFFSTACK When CONFIGCPUMASKOFFSTACK and CONFIGDEBUGPERCPUMAPS are selected, cpumaxbitswarn generates a runtime warning similar to the following, while we display /proc/cpuinfo. This...

Astra Linux – Vulnerability in exiv2

In Jp2Image::readMetadata in jp2image.cpp in Exiv2 0.27.2, an input file may lead to an infinite loop and system hangs, accompanied by high CPU consumption. Remote attackers could exploit this vulnerability to cause a denial of service by using a specially crafted file...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: cpufreq: CPPC: Fixed a possible nullptrderef issue in cpufreqcpugetraw. cpufreqcpugetraw may return NULL if the CPU is not included in policy-cpus cpu mask, which could lead to a null pointer dereference...

Astra Linux – Vulnerability in Linux 6.1

Improper initialization of the CPU cache memory could allow a privileged attacker with access to the hypervisor to overwrite the SEV-SNP guest memory, resulting in loss of data integrity...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: AppArmor: Fixed the rlimit settings for posix cpu timers. posix cpu timers require an additional step beyond simply setting rlimit. The code should be refactored so it’s clear which code is setting the limits, and the posix cp...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-6.1

A flaw in memory leak prevention in the Linux kernel’s cpuentryarea mechanism for mapping X86 CPU data to memory was discovered. This flaw allows a local user to guess the locations of exception stacks or other important data. By exploiting this flaw, a local user can gain access to certain...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: posix-cpu-timers: Clean up CPU timers before freeing them during exec. The commit 55e8c8eb2c7b “posix-cpu-timers: Store a reference to a pid instead of a task” introduced a mechanism to retrieve tasks by PID when deleting a CPU...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: RDMA/hns: Fixed the issue where the CPU got stuck due to printouts during reset. During reset, commands to destroy resources such as qp, cq, and mr may fail, and error logs will be printed. When a large number of resources are...

Astra Linux – Vulnerability in dovecot

The attacker can upload a malicious Sieve script through the ManageSieve service or locally to bypass the configured CPU time limits for Sieve up to 130 times the configured limit.
