Arch Linux Security Advisory ASA-201605-23
Date : 2016-05-18
CVE-ID : CVE-2015-1283 CVE-2016-0718
Package : lib32-expat
Type : arbitrary code execution
Remote : Yes
Link : https://wiki.archlinux.org/index.php/CVE
The package lib32-expat before version 2.1.1-2 is vulnerable to
arbitrary code execution.
Upgrade to 2.1.1-2.
# pacman -Syu "lib32-expat>=2.1.1-2"
The problems have been fixed upstream but no release is available yet.
- CVE-2015-1283 (arbitrary code execution)
Multiple integer overflows in the XML_GetBuffer function allow remote
attackers to cause a denial of service (heap-based buffer overflow) or
possibly arbitrary code execution via crafted XML data.
This problem has already been fixed in version 2.1.0-1 but this update
refreshes the fix to avoid relying on undefined behavior.
- CVE-2016-0718 (arbitrary code execution)
The Expat XML parser mishandles certain kinds of malformed input
documents, resulting in buffer overflows during processing and error
reporting. The overflows can manifest as a segmentation fault or as
memory corruption during a parse operation. The bugs allow for a denial
of service attack in many applications by an unauthenticated attacker,
and could conceivably result in remote code execution.
A remote attacker is able to use a specially crafted XML file that,
when processed, is leading to arbitrary code execution.
