UBUNTU-CVE-2026-78323

A flaw was found in JSS Java Security Services. The JSSTrustManager class does not verify NSS trust flags when validating CA certificates, allowing certificates present in the NSS database without TRUSTEDCA flags to be accepted as trust anchors for TLS connections. In non-default configurations...

Astra Linux – Vulnerabilities in Firefox, Thunderbird, NSS

A mismatch between the allocator and deallocator could have led to memory corruption. This vulnerability affects Firefox 128, Firefox ESR 115.13, Thunderbird 115.13, and Thunderbird 128...

Astra Linux – Vulnerabilities in Firefox, Thunderbird, NSS

NSS was vulnerable to a timing-side-channel attack during RSA decryption. This attack could potentially allow an attacker to retrieve private data. This vulnerability affects Firefox 124, Firefox ESR 115.9, and Thunderbird 115.9...

Astra Linux – Vulnerabilities in Firefox, Thunderbird, NSS

An unchecked return value in the TLS handshake code could have caused a potentially exploitable crash. This vulnerability affects Firefox 122, Firefox ESR 115.9, and Thunderbird 115.9...

Astra Linux – Vulnerability in nss

During RSA key generation, bignum implementations used a variant of the Binary Extended Euclidean Algorithm, which involved significant input-dependent processes. This allowed attackers to perform electromagnetic-based side-channel attacks to capture traces that could lead to the recovery of secr...

Astra Linux – Vulnerability in nss

A flaw was discovered in the way NSS handled CCS ChangeCipherSpec messages in TLS 1.3. This flaw allows a remote attacker to send multiple CCS messages, resulting in a denial of service for servers compiled with the NSS library. The greatest threat posed by this vulnerability is related to system...

Astra Linux – Vulnerability in nss

NSS has demonstrated timing differences during the execution of DSA signatures, which can be exploited and may eventually lead to the leakage of private keys. This vulnerability affects Thunderbird versions 68.9.0, Firefox versions 77, and Firefox ESR versions 68.9...

Astra Linux – Vulnerability in nss

A flaw was discovered in the implementation of CHACHA20-POLY1305 in NSS versions prior to 3.55. When using multi-part Chacha20, it could lead to out-of-bounds reads. This issue was addressed by explicitly disabling multi-part ChaCha20 which was not functioning correctly and enforcing strict tag...

UBUNTU-CVE-2026-68744

A flaw was found in SSSD. The sssnssprotocolfillinitgr function in the NSS responder pre-allocates reply space for all group entries but does not shrink the packet when groups are skipped, causing uninitialized heap bytes to be transmitted to the client. A local attacker can exploit this to...
