Drew Yao discovered that libxml2 did not correctly handle certain corrupt
XML documents. If a user or automated system were tricked into processing
a malicious XML document, a remote attacker could cause applications
linked against libxml2 to enter an infinite loop, leading to a denial
of service. (CVE-2008-4225)
Drew Yao discovered that libxml2 did not correctly handle large memory
allocations. If a user or automated system were tricked into processing a
very large XML document, a remote attacker could cause applications linked
against libxml2 to crash, leading to a denial of service. (CVE-2008-4226)
Solution:
The problem can be corrected by upgrading your system to the
following package versions:
Ubuntu 6.06 LTS:
