Qlustar Security Advisory 0430132

April 30, 2013


Summary:

Security bundle. A Qlustar security bundle is a cumulative update of packages that are taken from upstream Debian/Ubuntu without modification.

Other non-HPC related updates also enter the Qlustar repository, but their functionality is not separately verified by the Qlustar team. To track these updates subscribe to the general security mailing lists of Debian/Ubuntu.

This update includes several security related package updates from Debian/Ubuntu. The following list provides references to the upstream security report of the corresponding packages.

libxml2 vulnerability

It was discovered that libxml2 incorrectly handled XML entity expansion. An attacker could use this flaw to cause libxml2 to consume large amounts of resources, resulting in a denial of service.

Bind vulnerability

Matthew Horsfall discovered that Bind incorrectly handled regular expression checking. A remote attacker could use this flaw to cause Bind to consume an excessive amount of memory, possibly resulting in a denial of service. This issue was corrected by disabling RDATA regular expression syntax checking.

curl vulnerability

YAMADA Yasuharu discovered that libcurl was vulnerable to a cookie leak when doing requests across domains with matching tails. curl did not properly restrict cookies to domains and subdomains. If a user or automated system were tricked into processing a specially crafted URL, an attacker could read cookie values stored ...

Samba vulnerability

It was discovered that Samba incorrectly handled CIFS share attributes when SMB2 was used. A remote authenticated user could possibly gain write access to certain shares, bypassing the intended permissions.

Update instructions:
