In the Linux kernel, the following vulnerability has been resolved: In the net:sock section, the issue of a “hardened usercopy panic” in sockrecverrqueue has been fixed. The skbufffclonecache structure was created without defining a usercopy region. Unlike the skbuffheadcache, which properly...

Astra Linux – Vulnerability in Squid

Squid is a caching proxy for the Web. Prior to version 7.5, due to improper input validation, Squid was vulnerable to out-of-bound reads when handling ICP traffic. This issue allowed a remote attacker to access small amounts of memory that might contain sensitive information, by responding with...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: mm, slub: fixed a potential memory leak in kmemcacheopen. In the error path, the slub cache’s randomseq value might be leaked. This issue was addressed by using kmemcacherelease to release all relevant resources...
