Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, a malicious RDP server could trigger a heap buffer overflow in FreeRDP clients by using the GDI surface pipeline e.g., xfreerdp to send an RDPGFX ClearCodec surface command with an out-of-bounds destination...

Astra Linux – Vulnerability in Linux 5.15

The Linux kernel’s NFSD implementation before versions 5.19.17 and 6.0.2 is vulnerable to buffer overflow attacks. NFSD tracks the number of pages held by each NFSD thread by combining the receive and send buffers of a remote procedure call RPC into a single array of pages. A client can force the...
