Description:

The remote host is affected by the vulnerability described in GLSA-200410-31
(Archive::Zip: Virus detection evasion)


Archive::Zip can be used by email scanning software (like amavisd-new) to
uncompress attachments before virus scanning. By modifying the uncompressed
size of archived files in the global header of the ZIP file, it is possible
to fool Archive::Zip into thinking some files inside the archive have zero
length.

Impact

An attacker could send a carefully crafted ZIP archive containing a virus
file and evade detection on some email virus-scanning software relying on
Archive::Zip for decompression.

Workaround

There is no known workaround at this time.

Solution:
All Archive::Zip users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-perl/Archive-Zip-1.14"


Risk factor : Low
