Debian DLA-275-1 : ruby1.9.1 security update

high Nessus Plugin ID 84833

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that the uri package in the Ruby standard library uses regular expressions that may result in excessive backtracking.
Ruby applications that parse untrusted URIs using this library were susceptible to denial of service attacks by passing crafted URIs.

For the oldoldstable distribution (squeeze), this problem has been fixed in version 1.9.2.0-2+deb6u6.

The oldstable distribution (wheezy) and stable distribution (jessie) were not affected by this problem as it was fixed before release.

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.
