Description:
Two vulnerabilities have been reported in Libxml2, which can be exploited by malicious people to cause a DoS (Denial of Service) or to potentially compromise an application using the library.
1) An integer overflow error in the "xmlSAX2Characters()" function can be exploited to trigger a memory corruption via a specially crafted XML file.
Successful exploitation may allow execution of arbitrary code, but requires e.g. that the user is tricked into processing an overly large XML file (2GB or more).
2) An integer overflow error in the "xmlBufferResize()" function can be exploited to trigger the execution of an infinite loop.
The vulnerabilities are reported in version 2.7.2. Other versions may also be affected.
