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

In the Linux kernel, the following vulnerabilities have been resolved: net/iucv: Fixed the size of interrupt data iucvirqdata needs to be 4 bytes larger. These bytes are not used by the iucv module, but are written by the z/VM hypervisor in case a CPU is deconfigured. Reported as: BUG...

Astra Linux – Vulnerability in cairosvg

CairoSVG is an SVG converter based on Cairo, a 2D graphics library. Prior to Kozea/CairoSVG, there was exponential denial of service due to recursive elements being amplified in the cairosvg/defs.py file. This caused CPU exhaustion with even small inputs...

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. This allows the attacker to degrade server performance and bypass the configured CPU time limits for Sieve scripts. ...

In the Linux kernel, the following vulnerabilities have been resolved: media: rc: gpio-ir-recv: added/removed functions If runtime PM is enabled, perform runtime PM cleanup to remove the cpu latency QoS request. Otherwise, driver removal may result in the following kernel dump: 19.463299 Unable t...

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 5.10

In the Linux kernel, the following vulnerability has been resolved: cpufreq: qcom: fixed a memory leak in the error path. If, for some reason, the speedbin length is incorrect, then there is a memory leak in the error path, as we never free the speedbin buffer. This commit fixes this issue by...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: sched/rt: The function rtonextcpu should now properly handle situations where only CPU0 is overloaded. In such cases, rtonextcpu should ideally return -1, indicating that no further IPIs are needed. The vulnerability arises when...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: net: openvswitch: Fixed a race condition related to port output. Assume the following setup on a single machine: 1. An openvswitch instance with one bridge and default flows. 2. Two network namespaces: “server” and “client”. 3...

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 – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: arm64: dts: qcom: msm8998: Fixed the latency and residency issues during CPU/L2 idle states. The entry/exit latency and minimum residency in the idle states of the MSM8998 device were incorrect. Firstly, the timings were set for...

Astra Linux – Vulnerability in libpgjava

pgjdbc is an open-source PostgreSQL JDBC Driver. From version 42.2.0 to before version 42.7.11, pgjdbc was vulnerable to a client-side denial of service during SCRAM-SHA-256 authentication. A malicious server could instruct the driver to perform SCRAM authentication with a very large iteration...

Astra Linux – Vulnerability in libxstream-java

XStream is an open-source Java library for serializing objects to XML and back. Versions prior to 1.4.19 may allow a remote attacker to allocate 100% of the CPU time on the target system, depending on the CPU type or through parallel execution of such operations. This can lead to a denial of...
