Base vector

AV:N/AC:H/Au:N/C:N/I:N/A:P

Name of the Vulnerable Software and Affected Versions libxml2 version 2.9.1

Description The issue is related to the xz decomp function in xzlib.c, which does not properly handle compression errors. This allows attackers to cause a denial of service, resulting in a process hang, by providing crafted XML data. The vulnerability is also associated with resource management errors, and its exploitation can lead to a denial of service when specially formed XML data is used.

Recommendations For libxml2 version 2.9.1, consider updating to a newer version that addresses the issue with the xz decomp function. As a temporary workaround, restrict the use of crafted XML data to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
