CWE-785: Use of Path Manipulation Function without Maximum-sized Buffer
ID
CWE-785
Abstraction
Variant
Structure
Simple
Status
Incomplete
The product invokes a function for normalizing paths or file names, but it provides an output buffer that is smaller than the maximum possible size, such as PATH_MAX.
Passing an inadequately-sized output buffer to a path manipulation function can result in a buffer overflow. Such functions include realpath(), readlink(), PathAppend(), and others.
