FreeBSD : libxml2 -- entity substitution DoS (efdd0edc-da3d-11e3-9ecb-2c4138874f7d)
Medium Nessus Plugin ID 73975
SynopsisThe remote FreeBSD host is missing one or more security-related updates.
DescriptionStefan Cornelius reports :
It was discovered that libxml2, a library providing support to read, modify and write XML files, incorrectly performs entity substitution in the doctype prolog, even if the application using libxml2 disabled any entity substitution. A remote attacker could provide a specially crafted XML file that, when processed, would lead to the exhaustion of CPU and memory resources or file descriptors.
This issue was discovered by Daniel Berrange of Red Hat.
SolutionUpdate the affected packages.
