Vulnerability mechanics
Root cause
"An out-of-bounds write occurs in the `store32` function due to improper handling of data sizes when writing to memory."
Attack vector
An attacker can trigger this vulnerability by providing a specially crafted .gig or .DLS file to a libgig-based application. The vulnerability is triggered during file parsing, specifically when the `store32` function attempts to write data. This can lead to a crash or potentially more severe memory corruption issues.
Affected code
The vulnerability resides in the `store32` function within the `helper.h` file. The reference write-ups also point to issues in `RIFF.cpp` and `gig.cpp` related to buffer overflows and out-of-bounds reads/writes during file processing.
What the fix does
The patch addresses the out-of-bounds write in the `store32` function by ensuring that the size of data being written does not exceed the allocated buffer. This is achieved by adding checks to prevent writing beyond the intended memory boundaries, thereby mitigating the risk of memory corruption and crashes.
Preconditions
- inputA specially crafted .gig or .DLS file.
