Background
Grok is an open-source image compression library that provides functionality for encoding and decoding images. It is widely used in various applications to optimize image storage and transmission. However, a stack-use-after-scope vulnerability has been discovered in the library, which can lead to potential security issues.
Vulnerability Detail
The stack-use-after-scope vulnerability in grok originates from a specific function called grk::WaveletReverse::decompress_partial_tile. This function is used for decompressing image tiles. The vulnerability occurs when the function attempts to write to a stack variable that has already gone out of scope. This can result in memory corruption and potentially lead to arbitrary code execution. The vulnerability has been reported through the OSS-Fuzz project.
