| Description: | Daniel Stenberg discovered that wget, a network utility to retrieve files from the Web using http and ftp, is vulnerable to the "Null Prefix Attacks Against SSL/TLS Certificates" published at the Blackhat conference some time ago. 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, this problem has been fixed in version 1.10.2-2+etch1. For the stable distribution, this problem has been fixed in version 1.11.4-2+lenny1. For the testing distribution, this problem will be fixed soon. For the unstable distribution, this problem has been fixed in version 1.12-1. We recommend that you upgrade your wget packages. |
