Description:
Neel Mehta and Alex Wheeler have reported some vulnerabilities in Clam AntiVirus, which can be exploited by malicious people to cause a DoS (Denial of Service) or compromise a vulnerable system.
1) Two integer overflow errors in "libclamav/tnef.c" when processing TNEF files can be exploited to cause a heap-based buffer overflow via a specially crafted TNEF file with a length value of -1 in the header.
2) An integer overflow error in "libclamav/chmunpack.c" can be exploited to cause a heap-based buffer overflow via a specially crafted CHM file with a chunk entry that has a filename length of -1.
3) A boundary error in "libclamav/fsg.c" when processing a FSG compressed file can cause a heap-based buffer overflow.
The vulnerabilities have been reported in versions 0.86.1 and prior.
Solution:
Update to version 0.86.2.
Provided and/or discovered by:
Neel Mehta and Alex Wheeler.
