Improper Restriction of Operations within the Bounds of a Memory Buffer


Severity Medium
Score 6.8/10


The "msrle_decode_pal4" function in "msrledec.c" in Libav before v10.7, v11.x before v11.4, and v12_dev0. It affects FFmpeg before 2.0.7, 2.1.x before 2.1.8, 2.2.x before 2.2.15, 2.3.x before 2.4.8, 2.5.x before 2.5.6, and 2.6.x before 2.6.2. This issue allows remote attackers to have unspecified impact via a crafted image, related to a pixel pointer, which triggers an out-of-bounds array access.

CWE-119 - Buffer Overflow

Buffer overflow attacks involve data transit and operations exceeding the restricted memory buffer, thereby corrupting or overwriting data in adjacent memory locations. Such overflow allows the attacker to run arbitrary code or manipulate the existing code to cause privilege escalation, data breach, denial of service, system crash and even complete system compromise. Given that languages such as C and C++ lack default safeguards against overwriting or accessing data in their memory, applications utilizing these languages are most susceptible to buffer overflows attacks.
