Astra Linux – Vulnerability in OpenSSL

Issue Summary: When using the low-level OCB API directly with AES-NI or other hardware-accelerated code paths, inputs whose length is not a multiple of 16 bytes may leave the final partial block unencrypted and unauthenticated. Impact Summary: The last 1–15 bytes of a message may be exposed in...

Astra Linux – Vulnerability in libssh

A flaw was discovered in libssh versions built with OpenSSL versions older than 3.0. The issue lies with the sshkdf function, which is responsible for key derivation. Due to inconsistent interpretation of return values, OpenSSL uses 0 to indicate failure, while libssh uses 0 for success. As a...

Astra Linux – Vulnerability in OpenSSL

Issue summary: Calling the OpenSSL API function SSLfreebuffers may cause memory to be accessed that was previously freed in some situations. Impact summary: Using memory that has already been freed can lead to various potential consequences, such as corruption of valid data, crashes, or execution...

Astra Linux – Vulnerability in OpenSSL

The function PEMreadbioex reads a PEM file from a BIO, parses, and decodes the “name” e.g., “CERTIFICATE”, any header data, and the payload data. If the function succeeds, the “nameout”, “header”, and “data” arguments are populated with pointers to buffers containing the relevant decoded data. Th...

Astra Linux – Vulnerability in OpenSSL

Issue summary: An application attempting to decrypt messages encrypted using password-based encryption in CMS can trigger an out-of-bounds read and write attack. Impact summary: This out-of-bounds read attack may cause a system crash, leading to a denial of service for the application. The...
