Debian DLA-1167-1 : ruby-yajl security update

high Nessus Plugin ID 104464

Language:

Synopsis

The remote Debian host is missing a security update.

Description

A vulnerability was found in ruby-yajl, an interface to Yajl, a JSON stream-based parser library. When a crafted JSON file is supplied to Yajl::Parser.new.parse, the whole ruby process crashes with a SIGABRT in the yajl_string_decode function in yajl_encode.c. This may result in a denial of service.

For Debian 7 'Wheezy', these problems have been fixed in version 1.1.0-2+deb7u1.

We recommend that you upgrade your ruby-yajl 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 ruby-yajl package.
