Description:
Ulf Härnhammar has discovered some vulnerabilities in unace, which can be exploited by malicious people to compromise a user's system.
1) An input validation error when extracting files compressed with ACE (.ace) makes it possible extract files to arbitrary locations outside the specified directory using the "../" directory traversal sequence or an absolute path.
The vulnerability has been confirmed in version 1.2b. Other versions may also be affected.
2) Some boundary errors in the processing of malicious ACE archives can be exploited to cause a buffer overflow by tricking a user into extracting, testing, or listing a specially crafted archive.
The vulnerabilities have been confirmed in version 1.2b. One of the buffer overflow vulnerabilities have also been reported in version 2.04, 2.2 and 2.5. Other versions may also be affected.
Successful exploitation may allow execution of arbitrary code.
