Debian DSA-2824-1 : curl - unchecked tls/ssl certificate host name

medium Nessus Plugin ID 71541

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Marc Deslauriers discovered that curl, a file retrieval tool, would mistakenly skip verifying the CN and SAN name fields when digital signature verification was disabled in the libcurl GnuTLS backend.

The default configuration for the curl package is not affected by this issue since the digital signature verification is enabled by default.

The oldstable distribution (squeeze) is not affected by this problem.

Solution

Upgrade the curl packages.

For the stable distribution (wheezy), this problem has been fixed in version 7.26.0-1+wheezy7.
