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 node-cipher-base

There is a vulnerability in improper input validation in the cipher-base module, which allows for manipulation of input data. This issue affects cipher-base version 1.0.4...

Astra Linux – Vulnerability in mbedtls

A timing side channel in mbedtlsssldecryptbuf in library/sslmsg.c in Trusted Firmware Mbed TLS from version 2.23.0 allows an attacker to obtain secret key information. This issue affects the CBC mode, as it involves a calculated time difference based on the padding length...

Astra Linux – Vulnerability in openssl1.0

Calls to the EVPCipherUpdate, EVPEncryptUpdate, and EVPDecryptUpdate functions may cause the output length argument to overflow in some cases where the input length is close to the maximum permissible length for integers on the platform. In such cases, the return value from the function call will...

Astra Linux – Vulnerability in OpenVPN

A vulnerability was discovered in OpenVPN 2.4.x prior to version 2.4.9. An attacker can inject a data channel v2 PDATAV2 packet using the victim’s peer-id. Normally, such packets are discarded. However, if this packet arrives before the data channel crypto parameters have been initialized, the...

Astra Linux – Vulnerability in python-cryptography

Cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. In affected versions, Cipher.updateinto would accept Python objects that implement the buffer protocol, but only provide immutable buffers. This would allow immutable objects such as bytes to b...

libkcapi: IV reuse in libkcapi one-shot symmetric cipher chunking causes cipher state reset across chunk boundaries

A flaw was found in libkcapi. When performing one-shot symmetric cipher operations on large inputs over 64 KiB in stateful modes such as Counter CTR or Cipher Block Chaining CBC, the library improperly reuses the Initialization Vector IV for each internal data chunk. A remote attacker could...
