Technical details
The vulnerability is a heap-based buffer overflow (CWE-122) in the decompression logic for .tvs session recording files, affecting versions 15.70 through 15.81 on Linux and macOS. A size mismatch during decompression results in out-of-bounds heap writes. Exploitation requires user interaction: a victim must be tricked into opening a specially crafted .tvs file via the "Play or convert recorded session" feature, but no elevated privileges are required.
