Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.22.0, the sdlPointerNew function freed memory upon failure. However, after that function called pointerfree, it would call sdlPointerFree to free the memory again, triggering a Universal Address Fault UAF in ASan...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: arm64: ftrace: consistently handles PLTs. Sometimes it is necessary to use a PLT entry to call a ftrace trampoline. This is handled by ftracemakecall and ftracemakenop, both of which have almost identical logic. However, this is...
