In the Linux kernel, the following vulnerability has been resolved: mlxbfgige: stop interface during shutdown The mlxbfgige driver intermittantly encounters a NULL pointer exception while the system is shutting down via "reboot" command. The mlxbfdriver will experience an exception right after...

Astra Linux – Vulnerability in curl

This flaw allows an attacker to insert cookies into a running program using libcurl, provided that certain conditions are met. Libcurl performs transfers. In its API, an application creates “easy handles”—individual handles used for single transfers. Libcurl provides a function called...

Astra Linux – Vulnerability in mbedtls

A issue was discovered in Mbed TLS before version 2.25.0 and before versions 2.16.9 LTS and 2.7.18 LTS. A NULL algorithm parameter entry resembles an array of REAL values with a size of zero; therefore, the certificate is considered valid. However, if the parameters do not match at all, then the...
