Synopsis
========
Multiple vulnerabilities have been found in 7-Zip, the worst of which
may allow execution of arbitrary code.
Background
==========
7-Zip is an open-source file archiver, an application used primarily to
compress files. 7-Zip uses its own 7z archive format, but can read and
write several other archive formats.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-arch/p7zip < 16.02-r1 >= 16.02-r1
Description
===========
Multiple vulnerabilities have been discovered in 7-Zip. Please review
the CVE identifiers referenced below for details.
Impact
======
A remote attacker could entice a user to open a specially crafted
archive file possibly resulting in execution of arbitrary code with the
privileges of the process or a Denial of Service condition.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All 7-Zip users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-arch/p7zip-16.02-r1"
