Astra Linux - Vulnerability in Golang-1.19

The go command may execute arbitrary code during compilation when using cgo. This can occur when running “go get” on a malicious module, or when running any other command that compiles unauthorized code. This issue can be triggered by linker flags, specified via the cgo LDFLAGS directive. Flags...

Astra Linux – Vulnerability in NTP

In NTP versions 4.2.8, 4.2.8p15, and 4.3.x, before 4.3.101, remote attackers could cause a denial of service memory consumption by sending packets. This occurs because memory is not released in situations where a CMAC key is used and associated with a CMAC algorithm in the ntp.keys file...

In the Linux kernel, the following vulnerability has been resolved: ibmvnic: Added a check for transmission to prevent skb leaks. Here’s a summary of how the driver stores a reference to an skb during transmission: 1. txbufffreemapconsumerindex-skb = newskb; 2. freemapconsumerindex =...

Astra Linux – Vulnerability in LibreOffice

LibreOffice supports digital signatures for ODF documents and macros within documents. It provides visual aids to indicate that the document has not been altered since the last signature, and that the signature is valid. A vulnerability in certificate validation in LibreOffice allowed attackers t...

In the Linux kernel, the following vulnerability has been resolved: net: stmmac – ensure that ptprate is not set to 0 before configuring EST. If the value of ptprate, which was previously recorded in the driver, happens to be 0, this invalid value will be propagated up to the EST configuration,...

Astra Linux – Vulnerability in NTP

In the mstolfp.c file within NTP 4.2.8p15, there is a buffer overflow vulnerability when adding a decimal point. An adversary may be able to attack a client’s ntpq process, but they cannot attack the ntpd process...

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 OpenLDAP

In OpenLDAP versions 2.4.57 and 2.5.x through 2.5.1alpha, an assertion failure in slapd can occur in the issuerAndThisUpdateCheck function due to a malicious packet. This leads to a denial of service daemon exits caused by a short timestamp. This issue is related to the schemainit.c file and the...

Astra Linux – Vulnerability in NTP

In the mstolfp.c file within NTP 4.2.8p15, there is a buffer overflow vulnerability when a \0' character is added. An adversary may be able to attack a client ntpq process, but they cannot attack the ntpd process...

Astra Linux – Vulnerability in Chromium

The use of after-free in WebRTC in Google Chrome before version 149.0.7827.53 allowed a remote attacker to execute arbitrary code within a sandbox through a crafted HTML page. Chromium security severity: Medium...
