CVE-2026-33986
EUVD-2026-1723330.03.2026, 22:16
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, in yuv_ensure_buffer() in libfreerdp/codec/h264.c, h264->width and h264->height are updated before the reallocation loop. If any winpr_aligned_recalloc() call fails, the function returns FALSE but width/height are already inflated. This issue has been patched in version 3.24.2.Enginsight

Common Weakness Enumeration
- CWE-122 - Heap-based Buffer OverflowA heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
- CWE-131 - Incorrect Calculation of Buffer SizeThe software does not correctly calculate the size to be used when allocating a buffer, which could lead to a buffer overflow.
