Description:
Some vulnerabilities have been reported in ClamAV, which potentially can be exploited by malicious people to cause a DoS (Denial of Service) and compromise a vulnerable system.
1) An integer overflow error within the PE header parser in the "cli_scanpe()" function in libclamav/pe.c can be exploited to cause a heap-based buffer overflow and execute arbitrary code on a vulnerable system via a specially crafted UPX file.
Successful exploitation requires that the ArchiveMaxFileSize option is disabled.
2) Some format string errors in the logging handling in "shared/output.c" may be exploited to execute arbitrary code.
3) An out-of-bounds memory access error in the "cli_bitset_test()" function in "ibclamav/others.c" may be exploited to cause a crash.
The vulnerabilities have been reported in version 0.88. Prior versions may also be affected.
