7-Zip released version 26.02 to address a remote code execution vulnerability in its handling of XZ-compressed data. The flaw, discovered by researcher Landon Peng, can be triggered through a specially crafted archive. If a user opens the malicious file, an attacker could exploit a heap-based buffer overflow to execute arbitrary code with the user’s privileges.
The developer has not released technical details about the vulnerability, but the version 26.02 code changes suggest the issue involved improper handling of available buffer space during XZ decompression.
