Debian DSA-2798-1 : curl - unchecked ssl certificate host name

medium Nessus Plugin ID 70985

Language:

Synopsis

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

Description

Scott Cantor discovered that curl, a file retrieval tool, would disable the CURLOPT_SSLVERIFYHOST check when the CURLOPT_SSL_VERIFYPEER setting was disabled. This would also disable ssl certificate host name checks when it should have only disabled verification of the certificate trust chain.

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

Solution

Upgrade the curl packages.

For the oldstable distribution (squeeze), this problem has been fixed in version 7.21.0-2.1+squeeze5.

For the stable distribution (wheezy), this problem has been fixed in version 7.26.0-1+wheezy5.
