GLSA-200603-05 : zoo: Stack-based buffer overflow

Medium Nessus Plugin ID 21022


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


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.


All zoo users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-arch/zoo-2.10-r1'
