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

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 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 in Python 2.7, Python 3.7

A issue was discovered in the comparedigest function in Lib/hmac.py in Python through 3.9.1. Constant-time-defeating optimizations were possible in the accumulator variable used in hmac.comparedigest...

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

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Avoid NULL dereferencing of the timing generator Why & How Check whether the assigned timing generator is NULL before accessing its functions, to prevent NULL dereferencing...

Astra Linux – Vulnerability in Tomcat9

A vulnerability related to observable timing discrepancies occurs when comparing AJP secrets in Apache Tomcat. This issue affects Apache Tomcat versions as follows: 11.0.0-M1 through 11.0.21, 10.1.0-M1 through 10.1.54, 9.0.0.M1 through 9.0.117, 8.5.0 through 8.5.100, and 7.0.0 through 7.0.109...

Astra Linux – Vulnerability in gnutls28

A timing side-channel vulnerability in the handling of RSA ClientKeyExchange messages was discovered in GnuTLS. This side-channel can be used to recover the key encrypted in the RSA ciphertext across a network, in a Bleichenbacher-style attack. To successfully decrypt the data, the attacker would...

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 mbedtls

The use of a broken or risky cryptographic algorithm in the function mbedtlsmpiexpmod in lignum.c in Mbed TLS for all versions prior to 3.0.0, 2.27.0, or 2.16.11 allows attackers with access to precise timing and memory access information typically from an untrusted operating system attacking a...

Astra Linux – Vulnerability in nss

The NSS code used for checking PKCS1 v1.5 was leaking information useful for launching Bleichenbacher-style attacks. Both the overall correctness of the padding and the length of the encrypted message were exposed through timing side-channels. By sending a large number of ciphertexts selected by...

Astra Linux – Vulnerability in dovecot

Doveadm credentials are verified through direct comparison, which is vulnerable to timing oracle attacks. An attacker can use this vulnerability to determine the configured credentials. Identifying these credentials allows them to gain full access to the affected component. Limit access to the...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: fbdev: In of: displaytiming, there is a fix for the refcount leak in ofgetdisplaytimings. The function ofparsephandle returns a devicenode with the refcount incremented. This value is stored in ‘entry’ and then copied to...

Astra Linux – Vulnerability in Zabbix

The execution time for a failed login differs when using a non-existent username compared to using an existing one...

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

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 Erlang

A vulnerability in the Observable Timing Discrepancy mechanism in Erlang/OTP’s SSH libraries modules sshauth and sshoptions allows unauthenticated remote users to enumerate usernames through timing side-channels during password authentication. When the SSH daemon is configured with the...

Astra Linux – Vulnerability in nss
