Description:
Some vulnerabilities have been reported in ClamAV, which can be exploited by malicious people to cause a DoS (Denial of Service) or to potentially compromise a vulnerable system.
1) An integer overflow error within the "cli_scanpe()" function in libclamav/pe.c can be exploited to cause a heap-based buffer overflow via a specially crafted PE file.
2) An error within the "unmew11()" function in libclamav/mew.c can be exploited to corrupt heap memory.
Successful exploitation may allow execution of arbitrary code.
The vulnerabilities are reported in versions prior to 0.92.1.
Solution:
Update to version 0.92.1.
Provided and/or discovered by:
1) Silvio Cesare, reported to the vendor via iDefense.
2) The vendor credits Elliot.
