An Undefined Behavior vulnerability exists in the zisofs decompression logic, caused by improper validation of a field (`pz_log2_bs`) read from ISO9660 Rock Ridge extensions. A remote attacker can exploit this by supplying a specially crafted ISO file. This can lead to incorrect memory allocation and potential application crashes, resulting in a denial-of-service (DoS)

An Undefined Behavior vulnerability exists in the zisofs decompression logic, caused by improper validation of a field (`pz_log2_bs`) read from ISO9660 Rock Ridge extensions. A remote attacker can exploit this by supplying a specially crafted ISO file. This can lead to incorrect memory allocation and potential application crashes, resulting in a denial-of-service (DoS) condition.","status":"published","published":"2026-03-19T15:16:28Z","modified":"2026-11-05T05:40:51Z","updated_at":"2026-11-05T16:41:24.800038Z"},{"id":"MGASA-2026-0241","title":"Updated libarchive packages fix security vulnerabilities","description":"The updated packages fix bugs including security ones.\n","status":"published","published":"2026-07-11T20:43:25Z","modified":"2026-07-11T20:45:04.766306553Z","updated_at":"2026-11-02T15:49:43.795591Z"},{"id":"MGASA-2026-0366","title":"Updated libarchive packages fix security vulnerabilities","description":"Double-free vulnerability in rar5 decompression logic via dangling\nfiltered_buf pointer in init_unpack().
