Vulnerability Spotlight: Memory corruption vulnerability in PowerISO’s DMG handler
Summary: Cisco Talos discovered a memory corruption vulnerability, TALOS-2021-1308 (CVE-2021-21871), in PowerISO's handler for DMG files, which could let an attacker execute code on a victim's machine by tricking a user into opening a specially crafted DMG file. PowerISO fixed the issue but did not change the version number on the fixed release, so users should confirm they are running version 7.9 with the most recent bug fixes, and Snort rules 57728 and 57729 detect exploitation attempts.
What you should know: The fix shipped without a version number change, so anyone checking version strings alone cannot tell a patched PowerISO 7.9 from a vulnerable one - and the exploit path is a user opening a single crafted DMG file.
