Description:
Two vulnerabilities have been reported in ClamAV, which can be exploited by malicious people to cause a DoS (Denial of Service), or potentially to compromise a vulnerable system.
1) A signedness error in "libclamav/upx.c" can potentially be exploited to cause a heap-based buffer overflow when processing a malformed UPX-compressed executable file with a negative value in the "NumberOfSections" attribute of the PE header.
2) An error in "libclamav/fsg.c" when sorting sections in a FSG (v1.33)-compressed executable file may cause an infinite loop when processing a specially-crafted file containing two sections with the same Relative Virtual Address (RVA).
The vulnerabilities have been reported in version 0.86.2 and prior.
