Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: ext4: Verify that the size of orphan files isn’t too large. In principle, orphan files can be arbitrarily large. However, orphan replay operations need to traverse those files, and all their buffers are stored in memory. Therefor...

Astra Linux – Vulnerability in nbdkit

There is a flaw in the “blocksize” filter of nbdkit that can be triggered by a specific type of client request. When a client requests block status information for a very large data range, exceeding a certain limit, it causes an internal error in nbdkit, resulting in a denial of service...

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...
