CVE-2013-2020

First published: Mon May 13 2013(Updated: )

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.
