Synopsis :

The remote Gentoo host is missing one or more security-related

Description :

The remote host is affected by the vulnerability described in GLSA-200702-12
(CHMlib: User-assisted remote execution of arbitrary code)

function resulting in a shift of the stack pointer to arbitrary memory

Impact :

An attacker could entice a user to open a specially crafted CHM file,
resulting in the execution of arbitrary code with the permissions of
the user viewing the file.

Workaround :

There is no known workaround at this time.
