Sun Solaris Libxml2 Data Processing Integer Overflow Vulnerabilities

Two vulnerabilities have been identified in Sun Solaris, which could be exploited by attackers to cause a denial of service or compromise a vulnerable system.

1. An integer overflow error in the "xmlSAX2Characters()" function when processing an overly large XML file, which could cause a memory corruption potentially leading to arbitrary code execution.

2. An integer overflow error in the "xmlBufferResize()" function when processing an overly large XML file, which could cause an infinite loop, leading to a denial of service condition.
