Debian Security Advisory DSA-1904-1 security@debian.org
http://www.debian.org/security/ Giuseppe Iuculano
October 09, 2009 http://www.debian.org/security/faq
- - ------------------------------------------------------------------------
Package : wget
Vulnerability : insufficient input validation
Problem type : remote
Debian-specific: no
Debian bug : 549293
CVE ID : CVE-2009-3490
Daniel Stenberg discovered that wget, a network utility to retrieve files from
the Web using http(s) 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 (etch), this problem has been fixed in
version 1.10.2-2+etch1.
For the stable distribution (lenny), this problem has been fixed in
version 1.11.4-2+lenny1.
For the testing distribution (squeeze), this problem will be fixed soon.
For the unstable distribution (sid), this problem has been fixed in
version 1.12-1.
We recommend that you upgrade your wget packages.
