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

A flaw was discovered in the Netfilter subsystem of the Linux kernel. The sctpmtcheck function did not validate the flagcount field properly. This flaw allows a local privileged CAPNETADMIN attacker to trigger an out-of-bounds read, resulting in a system crash or the disclosure of sensitive...

Astra Linux – Vulnerability in CGal

There are multiple code execution vulnerabilities in the Nef polygon-parsing functionality of CGAL libcgal CGAL-5.1.1. A specially crafted malformed file can lead to an out-of-bounds read and type confusion, which could result in code execution. An attacker can provide malicious input to trigger...

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: ntbhwswitchtec: Fixed a out-of-bounds situation in switchtecntbmwsettrans. There is a kernel API called ntbmwcleartrans, which passes 0 to both addr and size. This would cause xlatepos to become negative. 23.734156 switchtec...

Astra Linux – Vulnerability in CGal

There are multiple code execution vulnerabilities in the Nef polygon-parsing functionality of CGAL libcgal CGAL-5.1.1. A specially crafted, malformed file can lead to an out-of-bounds read and type confusion, which may result in code execution. An attacker can provide malicious input to trigger a...

Astra Linux – Vulnerability in CGal

There is a code execution vulnerability in the Nef polygon-parsing functionality of CGAL libcgal CGAL-5.1.1. There is also an oob read vulnerability in NefS2/SNCioparser.h: SNCioParser::readsface sfh-boundaryentryobjects Sloopof. A specially crafted, malformed file can lead to an out-of-bounds re...

Astra Linux – Vulnerability in Chromium

A single error in V8 in Google Chrome prior to version 141.0.7390.54 allowed a remote attacker to perform an out-of-bounds memory read through a crafted HTML page. Chromium security severity: Medium...

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

In the Linux kernel, the following vulnerability has been resolved: riscv: Use READONCENOCHECK in the imprecise unwinding stack mode. When CONFIGFRAMEPOINTER is not set, the stack unwinding function walkstackframe randomly reads from the stack. When KASAN is enabled, this can lead to the followin...

Astra Linux – Vulnerability in OpenCV

A out-of-bounds read was discovered in OpenCV prior to version 4.1.1. Specifically, the variable coarsestscale is assumed to be greater than or equal to finestscale within the calc/oclcalc functions in disflow.cpp. However, this assumption is incorrect when dealing with small images, resulting in...

Astra Linux – Vulnerability in libxml2

It was discovered that Xmlsoft Libxml2 v2.11.0 contains an out-of-bounds read vulnerability through the xmlSAX2StartElement function located at /libxml2/SAX2.c. This vulnerability allows attackers to cause a Denial of Service DoS by providing a crafted XML file. NOTE: the vendor’s position is tha...

Astra Linux – Vulnerability in OpenCV

A issue was discovered in OpenCV before versions 3.4.7 and 4.x before version 4.1.1. There is an out-of-bounds read/write operation in the function HaarEvaluator::OptFeature::calc in modules/objdetect/src/cascadedetect.hpp, which leads to a denial of service...

Astra Linux – Vulnerability in ntfs-3g

A properly crafted NTFS image can lead to a out-of-bounds read in ntfsielookup in NTFS-3G before version 2021.8.22...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ext4: Fixed a potential out-of-bound read issue in ext4fcreplayscan. For the scan loop, it is necessary to ensure that at least EXT4FCTAGBASELEN space is available. If the remaining space is less than EXT4FCTAGBASELEN, it may lea...
