powerarchiver-loadtree-readheader-bo (31263) The risk level is classified as HighHigh Risk

Description:

PowerArchiver is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the LoadTree() and ReadHeader() functions in PAISO.DLL. By creating a specially-crafted ISO image containing files with overly long pathnames, a remote attacker could overflow a buffer and execute arbitrary code on the system, if the attacker could convince the victim to open the malicious ISO image.
