Technical details
A heap-based buffer overflow (CWE-122) exists in Adobe Format Plugins versions 1.1.2 and earlier. The vulnerability is triggered when the application improperly handles memory allocation while parsing a specially crafted file. An attacker can exploit this by convincing a user to open a malicious file, leading to arbitrary code execution in the context of the current user. The attack vector is local, requiring user interaction (UI:R) but no prior privileges (PR:N). Adobe has addressed this issue in later versions, and users are advised to update to the latest available release.
