Description:
Two vulnerabilities have been reported in Clam AntiVirus, which can be exploited by malicious people to cause a DoS (Denial of Service) or potentially compromise a vulnerable system.
1) An out-of-bounds memory access error in the CHM (Compressed HTML Help) unpacker in chmunpack.c can be exploited to crash the virus scanning service via a specially crafted CHM file.
2) An integer overflow error in rebuildpe.c when rebuilding PE files after unpacking can be exploited to cause a heap-based buffer overflow via a specially crafted executable.
Successful exploitation of this vulnerability may allow execution of arbitrary code.
The vulnerabilities are reported in version 0.88.4. Prior versions may also be affected.
