Debian DLA-959-1 : libical security update

Medium Nessus Plugin ID 100479


The remote Debian host is missing a security update.


It was discovered that there was a use-after-free vulnerability in the libical iCalendar library. Remote attackers could cause a denial of service and possibly read heap memory via a specially crafted .ICS file.

For Debian 7 'Wheezy', this issue has been fixed in libical version 0.48-2+deb7u1.

We recommend that you upgrade your libical packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Upgrade the affected libical-dbg, libical-dev, and libical0 packages.
