Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: SCTP: The comparison of MACs has been fixed to require constant-time operations. To prevent timing attacks, MACs need to be compared in constant-time. Use the appropriate helper function for this purpose...

Astra Linux – Vulnerability in Heimdal

The fix for CVE-2022-3437 involved changing the memcmp function to run in constant time, as well as providing a workaround for a compiler bug by adding comparisons of the result with the value “!= 0” to the memcmp function. When these patches were backported to the heimdal-7.7.1 and heimdal-7.8.0...
