Astra Linux – Vulnerability in Apache2

A timing attack against modauthdigest in Apache HTTP Server 2.4.66 allows a remote attacker to bypass Digest authentication. Users are recommended to upgrade to version 2.4.67, which fixes this issue...

Astra Linux – Vulnerability in libmojolicious-perl

The Mojolicious module prior to version 8.65 for Perl is vulnerable to securecompare timing attacks, which allow an attacker to guess the length of a secret string. Only versions after 1.74 are affected...

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 Firefox and Thunderbird

The error page for sites with invalid TLS certificates lacked the activation-delay feature provided by Firefox to protect prompts and permission dialogs from attacks that exploit human response time delays. If a malicious page triggered user clicks at specific locations immediately before...

Astra Linux – Vulnerability in libgcrypt20

It was discovered that there was an ECDSA timing attack in the libgcrypt20 cryptographic library. Affected versions: 1.8.4-5, 1.7.6-2+deb9u3, and 1.6.3-2+deb8u4. Fixed versions: 1.8.5-2 and 1.6.3-2+deb8u7...

Astra Linux – Vulnerability in Firefox and Thunderbird

By monitoring the time it takes for certain operations to complete, an attacker could figure out which external protocol handlers were functioning on a user’s system. This vulnerability affects Firefox 127, Firefox ESR 115.12, and Thunderbird 115.12...

Astra Linux – Vulnerability in nss

When converting coordinates from projective to affine, the modular inversion was not performed in constant time, allowing for a timing-based side channel attack. This vulnerability affects Firefox versions less than 80, as well as Firefox for Android versions less than 80...

Astra Linux – Vulnerability in nss

During ECDSA signature generation, padding is applied in the nonce to ensure that constant-time scalar multiplication is removed. However, this results in variable-time execution that depends on secret data. This vulnerability affects Firefox versions less than 80, as well as Firefox for Android...
