>> Libxml2 Buffer Overflow and Denial of Service Vulnerabilities
|
Two vulnerabilities have been identified in Libxml2, which could be exploited by attackers to cause a denial of service or compromise a vulnerable system.
The first issue is caused by a recursion error when processing malformed entities, which could allow attackers to cause a vulnerable application to exhaust all available memory resources via a specially crafted XML file.
The second vulnerability is caused by a buffer overflow error when processing overly long XML entity names, which could be exploited to crash an affected application or potentially execute arbitrary code.
Affected Products
Libxml2 versions 2.x
Solution
Upgrade to version 2.7.0.
