USN-3513-2: libxml2 vulnerability
13 December 2017
libxml2 could be made to crash or run arbitrary code if it opened a specially crafted file.
- libxml2 - GNOME XML library
USN-3513-1 fixed a vulnerability in libxml2. This update provides
the corresponding update for Ubuntu 12.04 ESM.
Original advisory details:
It was discovered that libxml2 incorrecty handled certain files. An attacker
could use this issue with specially constructed XML data to cause libxml2 to
consume resources, leading to a denial of service.
The problem can be corrected by updating your system to the following package versions:
- libxml2 - 2.7.8.dfsg-5.1ubuntu4.20
- libxml2-utils - 2.7.8.dfsg-5.1ubuntu4.20
- python-libxml2 - 2.7.8.dfsg-5.1ubuntu4.20
In general, a standard system update will make all the necessary changes.
