Walied Assar has discovered a vulnerability in PE Explorer, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to an error when parsing strings in the resource section within Portable Executable (PE) files. This can be exploited to cause a heap-based buffer overflow via a specially crafted resource string.
Successful exploitation allows execution of arbitrary code, but requires tricking a user into processing a file.
The vulnerability is confirmed in version 1.99 R6. Other versions may also be affected.
Solution: Do not open files from untrusted sources.
