A vulnerability has been discovered in mcrypt, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error in the "check_file_head()" function (src/extra.c) when processing the header of an encrypted file and can be exploited to cause a stack-based buffer overflow.
Successful exploitation may allow execution of arbitrary code, but requires tricking a user into decrypting a malicious file.
The vulnerability is confirmed in version 2.6.8. Other versions may also be affected.
Solution: No official solution is currently available.
