Arch Linux Security Advisory ASA-201603-23
Date : 2016-03-24
CVE-ID : CVE-2015-1283
Package : expat
Type : arbitrary code execution
Remote : Yes
Link : https://wiki.archlinux.org/index.php/CVE
The package expat before version 2.1.1-1 is vulnerable to several
integer overflows leading to arbitrary code execution.
Upgrade to 2.1.1-1.
# pacman -Syu "expat>=2.1.1-1"
The problem has been fixed upstream in version 2.1.1.
Multiple integer overflows in the XML_GetBuffer() function in Expat
through 2.1.0 allow remote attackers to cause a denial of service
(heap-based buffer overflow) or possibly have unspecified other impact
via crafted XML data, a related issue to CVE-2015-2716.
A remote attacker can execute arbitrary code on the affected host by
submitting a specially crafted XML file for parsing.
Note that Expat is used in several products, some of them accepting
untrusted XML files from the network.
