Details

Scott Cantor discovered that Curl did not correctly handle SSL
certificates with zero bytes in the Common Name. A remote attacker could
exploit this to perform a machine-in-the-middle attack to view sensitive
information or alter encrypted communications.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 9.04

• libcurl3 - 7.18.2-8ubuntu4.1

Ubuntu 8.10

• libcurl3 - 7.18.2-1ubuntu4.4

Ubuntu 8.04

• libcurl3 - 7.18.0-1ubuntu2.2

Ubuntu 6.06

• libcurl3 - 7.15.1-1ubuntu3.2

In general, a standard system upgrade is sufficient to effect the
necessary changes.
