Last modified
CVE-2013-2020 is a vulnerability of currently unknown severity. Integer underflow in the cli_scanpe function in pe.c in ClamAV before 0.97.8 allows remote attackers to cause a denial of service (crash) via a skewed offset larger than the size of the PE section in a UPX packed executable, which triggers an out-of-bounds read.. EPSS estimates a 3.55% chance of exploitation in the next 30 days.
