-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - ------------------------------------------------------------------------ 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. Upgrade instructions - -------------------- wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given below: apt-get update will update the internal database apt-get upgrade will install corrected packages You may use an automated update by adding the resources from the footer to the proper configuration.
