Astra Linux – Vulnerability in Firefox

The NSCDeriveKey function inadvertently assumed that the phKey parameter was always non-NULL. When the parameter was passed as NULL, a segmentation fault occurred, resulting in crashes. This behavior conflicts with the PKCS11 v3.0 specification, which allows phKey to be NULL for certain mechanism...

In the Linux kernel, the following vulnerability has been resolved: btrfs: Fixed an invalid leaf access in btrfsquotaenable if the ref key is not found. If btrfssearchslotforread returns 1, it means that we did not find any key that is greater than or equal to the key we requested. This means tha...

Astra Linux – vulnerability in mbedtls

Mbed TLS versions prior to 3.6.4 contain a race condition in AESNI detection when certain compiler optimizations are applied. An attacker may be able to extract an AES key from a multithreaded program, or perform a GCM forgery...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: A missing key size check in L2CAPLECONNREQ has been fixed. A check for the encryption key size is added upon receiving the L2CAPLECONNREQ. This is required by L2CAP/LE/CFC/BV-15-C, which expects...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: libceph: Defined and enforced the CEPHMAXKEYLEN. When decoding the key, verify that the key material fits into a fixed-size buffer in processauthdone, and that its length is reasonable. The new CEPHMAXKEYLEN check replaces the...

In the Linux kernel, the following vulnerabilities have been resolved: smb: client: rejecting descriptions of cifs.spnego in user space Descriptions of cifs.spnego keys contain fields that carry authority, such as pid, uid, creduid, and upcalltarget. The cifs.upcall treats these fields as...

Astra Linux – vulnerability in munge

MUNGE is an authentication service used to create and validate user credentials. In versions 0.5 through 0.5.17, a local attacker can exploit a buffer overflow vulnerability in munged the MUNGE authentication daemon to leak cryptographic key material from process memory. Using this leaked key...

Astra Linux – Vulnerability in mbedtls

A vulnerability was discovered in Arm Mbed TLS prior to version 2.24.0. An attacker can obtain a private key for RSA or static Diffie-Hellman through a side-channel attack targeting the generation of base blinding/unblinding values...

Astra Linux – Vulnerability in Consul

The HashiCorp Consul and Consul Enterprise versions up to 1.9.4 had a key-value KV raw mode that was vulnerable to cross-site scripting attacks. This issue was fixed in versions 1.9.5, 1.8.10, and 1.7.14...

Astra Linux – Vulnerability in Node-Elliptic

The ECDSA implementation of the Elliptic package generates incorrect signatures if the intermediate value ‘k’ calculated based on step 3.2 of RFC 6979 https://datatracker.ietf.org/doc/html/rfc6979 has leading zeros and is susceptible to cryptanalysis, which can lead to the exposure of the secret...

Astra Linux – Vulnerability in Redis

Valkey is a distributed key-value database. Prior to versions 9.0.2, 8.1.6, 8.0.7, and 7.2.12, a malicious user could use scripting commands to inject arbitrary information into the response stream for a given client, potentially corrupting or returning tampered data to other users on the same...
