Debian 4.0 DSA-1869-1 Critical: Curl SSL Certificate Issue

It was discovered that curl, a client and library to get files from serversusing HTTP, HTTPS or FTP, is vulnerable to the "Null Prefix Attacks Against
SSL/TLS Certificates" recently published at the Blackhat conference. This
allows an attacker to perform undetected man-in-the-middle attacks via a
crafted ITU-T X.509 certificate with an injected null byte in the Common
Name field.


For the oldstable distribution (etch), this problem has been fixed in
version 7.15.5-1etch3.

For the stable distribution (lenny), this problem has been fixed in
version 7.18.2-8lenny3.

For the testing (squeeze) and unstable (sid) distribution, this problem
will be fixed soon.


We recommend that you upgrade your curl packages.
