Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: bnxten: The backing store type is set based on the query type. The bnxthwrmfuncbackingstoreqcapsv2 function stores resp-type from the firmware response in ctxm-type. This value is then used to index fixed backing-store metadata...

Astra Linux – Vulnerability in JRuby

Versions of Ruby from 2.4.7, 2.5.x up to 2.5.6, and 2.6.x up to 2.6.4 allow HTTP Response Splitting. If a program using WEBrick inserts untrusted input into the response header, an attacker can exploit this to insert a newline character to split the header, thereby injecting malicious content to...
