Improper Restriction of Operations within the Bounds of a Memory Buffer
Stack-based buffer overflow in the (1) diff_addremove and (2) diff_change functions in GIT before 18.104.22.168 might allow local users to execute arbitrary code via a PATH whose length is larger than the system's PATH_MAX when running GIT utilities such as git-diff or git-grep.
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.
