High Nessus Plugin ID 44739
SynopsisThe remote Debian host is missing a security-related update.
DescriptionSeveral vulnerabilities have been discovered in the Network Security Service libraries. The Common Vulnerabilities and Exposures project identifies the following problems :
- CVE-2009-2404 Moxie Marlinspike discovered that a buffer overflow in the regular expression parser could lead to the execution of arbitrary code.
- CVE-2009-2408 Dan Kaminsky discovered that NULL characters in certificate names could lead to man-in-the-middle attacks by tricking the user into accepting a rogue certificate.
- CVE-2009-2409 Certificates with MD2 hash signatures are no longer accepted since they're no longer considered cryptograhically secure.
SolutionUpgrade the nss packages.
The old stable distribution (etch) doesn't contain nss.
For the stable distribution (lenny), these problems have been fixed in version 188.8.131.52-0lenny1.
