Debian Security Advisory
DSA-1904-1 wget -- insufficient input validation
- Date Reported:
- 09 Oct 2009
- Affected Packages:
- wget
- Vulnerable:
- Yes
- Security database references:
- In the Debian bugtracking system: Bug 549293.
In Mitre's CVE dictionary: CVE-2009-3490. - More information:
-
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.
