Xml · Libxml2 · CVE-2009-2414
**Name of the Vulnerable Software and Affected Versions**
libxml2 versions 2.5.10, 2.6.16, 2.6.26, 2.6.27, and 2.6.32
libxml version 1.8.17
libxml2 versions prior to 2.7.3
**Description**
The issue is related to a stack consumption vulnerability in libxml2, allowing context-dependent attackers to cause a denial of service (application crash) via a large depth of element declarations in a DTD. This is related to a function recursion. The vulnerability can be exploited remotely, leading to a disruption of protected information.
**Recommendations**
For libxml2 versions 2.5.10, 2.6.16, 2.6.26, 2.6.27, and 2.6.32, update to version 2.7.3 or later.
For libxml version 1.8.17, update to a version later than 1.8.17.
For libxml2 versions prior to 2.7.3, update to version 2.7.3 or later.
As a temporary workaround, consider restricting the use of the `libxml2` library until a patch is available.
