FreeBSD : clamav -- Multiple Vulnerabilities (589d8053-0b03-11dd-b4ef-00e07dc4ec84)
Critical Nessus Plugin ID 31983
SynopsisThe remote FreeBSD host is missing one or more security-related updates.
DescriptionSecunia reports :
Some vulnerabilities have been reported in ClamAV, which can be exploited by malicious people to cause a DoS (Denial of Service) or to compromise a vulnerable system.
1) A boundary error exists within the 'cli_scanpe()' function in libclamav/pe.c. This can be exploited to cause a heap-based buffer overflow via a specially crafted 'Upack' executable.
Successful exploitation allows execution of arbitrary code.
2) A boundary error within the processing of PeSpin packed executables in libclamav/spin.c can be exploited to cause a heap-based buffer overflow.
Successful exploitation may allow execution of arbitrary code.
3) An unspecified error in the processing of ARJ files can be exploited to hang ClamAV.
SolutionUpdate the affected packages.
