Title: Zsh: User-assisted execution of arbitrary code
Date: March 10, 2019
Bugs: #665278
ID: 201903-02
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
Input validation errors in Zsh could result in arbitrary code
execution.
Background
==========
A shell designed for interactive use, although it is also a powerful
scripting language.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-shells/zsh < 5.6 >= 5.6
Description
===========
Two input validation errors have been discovered in how Zsh parses
scripts:
* Parsing a malformed shebang line could cause Zsh to call a program
listed in the second line (CVE-2018-0502)
* Shebang lines longer than 64 characters are truncated
(CVE-2018-13259)
Impact
======
An attacker could entice a user to execute a specially crafted script
using Zsh, possibly resulting in execution of arbitrary code with the
privileges of the process.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Zsh users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-shells/zsh-5.6"
