Information Disclosure Buffer Overflow

Description

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, there is a heap-buffer-overflow READ vulnerability at 24 bytes before the allocation, in winpr_aligned_offset_recalloc(). This issue has been patched in version 3.24.2.

Analysis

Heap-buffer-overflow in FreeRDP's winpr_aligned_offset_recalloc() function allows local attackers with no privileges but requiring user interaction to trigger high-severity information disclosure and denial of service in versions prior to 3.24.2. The vulnerability involves a READ operation at 24 bytes before heap allocation boundaries (CWE-125: Out-of-bounds Read). …
