Package : icoutils
Type    : arbitrary code execution
Remote  : No
Link    : https://security.archlinux.org/AVG-129

Summary
=======

The package icoutils before version 0.31.1-1 is vulnerable to arbitrary
code execution.

Resolution
==========

Upgrade to 0.31.1-1.

# pacman -Syu "icoutils>=0.31.1-1"

The problem has been fixed upstream in version 0.31.1.

Workaround
==========

None.

Description
===========

An integer overflow vulnerability was found in icoutils in the wrestool
program. A maliciously crafted file could make the application crash or
possibly lead to arbitrary code execution. This issue only affects
64-bit systems, as the result of subtracting two pointers exceeds the
size of int.

Impact
======

An attacker is able to execute arbitrary code on a target machine by
tricking the user to open a specially crafted file.
