The remote Debian host is missing a security-related update.Description
Rauli Kaksonen, Tero Rontti and Jukka Taimisto discovered several vulnerabilities in libxml, a library for parsing and handling XML data files, which can lead to denial of service conditions or possibly arbitrary code execution in the application using the library. The Common Vulnerabilities and Exposures project identifies the following problems :- CVE-2009-2416 An XML document with specially crafted Notation or Enumeration attribute types in a DTD definition leads to the use of a pointers to memory areas which have already been freed.
- CVE-2009-2414 Missing checks for the depth of ELEMENT DTD definitions when parsing child content can lead to extensive stack-growth due to a function recursion which can be triggered via a crafted XML document.
Solution
Upgrade the libxml packages.For the oldstable distribution (etch), this problem has been fixed in version 1.8.17-14+etch1.
The stable (lenny), testing (squeeze) and unstable (sid) distribution do not contain libxml anymore but libxml2 for which DSA-1859-1 has been released.
