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...

Amazon Linux 2023 : gnutls, gnutls-c++, gnutls-dane (ALAS2023-2026-1808)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1808 advisory. Permitted name constraints were wrongfully ignored when prior CAs only had excluded name constraints, resulting in a name constraint bypass. The issue was reported in the issue tracker as 1824...

Medium: gnutls

Issue Overview: Permitted name constraints were wrongfully ignored when prior CAs only had excluded name constraints, resulting in a name constraint bypass. The issue was reported in the issue tracker as 1824 by Haruto Kimura Stella. CVE-2026-42011 Certificates containing URI or SRV Subject...

Siemens SIMATIC S7-1500 Observable Discrepancy (CVE-2023-5981)

A vulnerability was found that the response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from response times of ciphertexts with correct PKCS1 v1.5 padding. This plugin only works with Tenable.ot. Please visit https://www.tenable.com/products/tenable-ot for more information...

CLSA-2024-1732197150 Fix of 20 CVEs

Update to 8u432-ga fixing a number of CVEs - CVE-2024-20918: missing array range check in C1 compiler leads to out-of-bounds access - CVE-2024-20919: unverified bytecode execution because of the flaw in JVM class file verifier - CVE-2024-20921: optimization issue of loop range check in IfNode and...

PT-2024-1281

Name of the Vulnerable Software and Affected Versions GnuTLS affected versions not specified Description The issue is related to a difference in response time when handling RSA ciphertext in ClientKeyExchange messages with correct and incorrect PKCS1 padding. This could allow a remote attacker to...

SUSE CVE-2013-1624

The TLS implementation in the Bouncy Castle Java library before 1.48 and C library before 1.8 does not properly consider timing side-channel attacks on a noncompliant MAC check operation during the processing of malformed CBC padding, which allows remote attackers to conduct distinguishing attack...

The vulnerability of the Cisco Unified Communications Manager software allows a malicious individual to obtain a one-time code (nonce) for an ECDSA encryption algorithm.

The vulnerability exists in the implementation of the Montgomery algorithm in OpenSSL, due to the temporal impermanence of the operations involved in padding. Exploiting this vulnerability allows local users to obtain a one-time code nonce for ECDSA by attacking the cache through external channel...

OpenJDK: RSA unpadding timing issues (Security, 8027766)

Unspecified vulnerability in Oracle Java SE 5.0u61, 6u71, 7u51, and 8; JRockit R27.8.1 and R28.3.1; and Java SE Embedded 7u51 allows remote attackers to affect confidentiality and integrity via unknown vectors related to Security...

bouncycastle: TLS CBC padding timing attack

It was discovered that bouncycastle leaked timing information when decrypting TLS/SSL protocol encrypted records when CBC-mode cipher suites were used. A remote attacker could possibly use this flaw to retrieve plain text from the encrypted packets by using a TLS/SSL server as a padding oracle...
