Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200603-05
(zoo: Stack-based buffer overflow)

Jean-Sebastien Guay-Leroux discovered a boundary error in the
fullpath() function in misc.c when processing overly long file and
directory names in ZOO archives.

Impact :

An attacker could craft a malicious ZOO archive and entice someone
to open it using zoo. This would trigger a stack-based buffer overflow
and potentially allow execution of arbitrary code with the rights of
the victim user.

Workaround :

There is no known workaround at this time.

# emerge --sync
# emerge --ask --oneshot --verbose '>=app-arch/zoo-2.10-r1'
