Debian DLA-273-1 : tidy security update

medium Nessus Plugin ID 84831

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Fernando Muñoz discovered a security issue on the HTML syntax checker and reformatter tidy. Tidy did not properly process specific character sequences, and a remote attacker could exploit this flaw to cause a DoS, or probably, execute arbitrary code. Two different CVEs were assigned to this issue.

CVE-2015-5522

Malformed html documents could lead to a heap-buffer-overflow.

CVE-2015-5523

Malformed html documents could lead to allocate 4Gb of memory.

For the Squeeze distribution, this issue has been fixed in the 20091223cvs-1+deb6u1 version of tidy.

We recommend that you upgrade your tidy 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.

Solution

Upgrade the affected packages.
