It was discovered that KDE-Libs did not properly handle certain malformed SVG images. If a user were tricked into opening a specially crafted SVG image, an attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. This issue only affected Ubuntu 9.04. (CVE-2009-0945) [More...]

Ubuntu 802-2: Apache regression

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

USN-802-1 fixed vulnerabilities in Apache. The upstream fix for CVE-2009-1891 introduced a regression that would cause Apache children to occasionally segfault when mod_deflate is used. This update fixes the problem. [More...]

Ubuntu 819-1: Linux kernel vulnerability

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Tavis Ormandy and Julien Tinnes discovered that Linux did not correctlyinitialize certain socket operation function pointers. A local attackercould exploit this to gain root privileges. By default, Ubuntu 8.04and later with a non-zero /proc/sys/vm/mmap_min_addr setting were notvulnerable. [More...]

Ubuntu 818-1: curl vulnerability

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Scott Cantor discovered that Curl did not correctly handle SSLcertificates with zero bytes in the Common Name. A remote attacker couldexploit this to perform a man in the middle attack to view sensitiveinformation or alter encrypted communications. [More...]

Ubuntu 816-1: fetchmail vulnerability

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Moxie Marlinspike discovered that fetchmail did not properly handlecertificates with NULL characters in the certificate name. A remoteattacker could exploit this to perform a man in the middle attack toview sensitive information or alter encrypted communications. [More...]

Ubuntu 815-1: libxml2 vulnerabilities

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

It was discovered that libxml2 did not correctly handle root XML document element DTD definitions. If a user were tricked into processing a specially crafted XML document, a remote attacker could cause the application linked against libxml2 to crash, leading to a denial of service.
