Arch Linux Security Advisory ASA-201803-23
Date : 2018-03-25
CVE-ID : CVE-2017-12627
Package : xerces-c
Type : arbitrary code execution
Remote : Yes
Link : https://security.archlinux.org/AVG-644
The package xerces-c before version 3.2.1-1 is vulnerable to arbitrary
Upgrade to 3.2.1-1.
# pacman -Syu "xerces-c>=3.2.1-1"
The problem has been fixed upstream in version 3.2.1.
The Xerces-C XML parser mishandles certain kinds of external DTD
references, resulting in dereference of a NULL pointer while processing
the path to the DTD. The bug allows for a denial of service attack in
applications that allow DTD processing and do not prevent external DTD
usage, and could conceivably result in remote code execution.
A remote attacker might be able to cause a denial of service or execute
arbitrary code by submitting a crafted XML document with an external
DTD path to an application using a vulnerable version of the xerces-c
