Name of the Vulnerable Software and Affected Versions GTKWave version 3.3.115

Description A specially crafted .lxt2 file can lead to arbitrary code execution due to an out-of-bounds write vulnerability in the LXT2 zlib block decompression functionality. A victim would need to open a malicious file to trigger this issue. The LXT2 zlib block decompression functionality is the vulnerable component, and the arbitrary code execution is the potential outcome of exploiting this vulnerability.

Recommendations For GTKWave version 3.3.115, consider avoiding the use of the LXT2 zlib block decompression functionality until a patch is available. As a temporary workaround, restrict the opening of .lxt2 files from untrusted sources to minimize the risk of exploitation.
