CVE-2026-42512

As dhclient is building an environment to pass to dhclient-script, it may need to resize the array of string pointers. The code which expands the array incorrectly calculates its new size when requesting memory, resulting in a heap buffer overrun. A specially crafted packet can cause dhclient to...

FreeRDP: FreeRDP: Heap buffer overflow allows arbitrary code execution via crafted pixel data

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. A remote attacker could exploit a heap buffer overflow vulnerability in the resizevbarentry function. This occurs when an error in buffer resizing leads to attacker-controlled pixel data being written into an...
