Ubuntu: KDE-Graphics vulnerabilities  24 August 2009 
Posted by Benjamin D. Thomas   
It was discovered that KDE-Graphics 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.
 
Ubuntu: libvorbis vulnerability  24 August 2009 
Posted by Benjamin D. Thomas   
It was discovered that libvorbis did not correctly handle certain malformed ogg files. If a user were tricked into opening a specially crafted ogg file with an application that uses libvorbis, an attacker could execute arbitrary code with the user's privileges. (CVE-2009-2663) USN-682-1 provided updated libvorbis packages to fix multiple security vulnerabilities. The upstream security patch to fix CVE-2008-1420 introduced a regression when reading sound files encoded with libvorbis 1.0beta1. This update corrects the problem. Original advisory details: It was discovered that libvorbis did not correctly handle certain malformed sound files. If a user were tricked into opening a specially crafted sound file with an application that uses libvorbis, an attacker could execute arbitrary code with the user's privileges. (CVE-2008-1420)
 
Ubuntu: KDE-Libs vulnerabilities  24 August 2009 
Posted by Benjamin D. Thomas   
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) It was discovered that the KDE JavaScript garbage collector did not properly handle memory allocation failures. If a user were tricked into viewing a malicious website, an attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2009-1687) It was discovered that KDE-Libs did not properly handle HTML content in the head element. If a user were tricked into viewing a malicious website, an attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2009-1690) It was discovered that KDE-Libs did not properly handle the Cascading Style Sheets (CSS) attr function call. If a user were tricked into viewing a malicious website, an attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2009-1698)
 
Ubuntu: Pidgin vulnerability  20 August 2009 
Posted by Benjamin D. Thomas   
Federico Muttis discovered that Pidgin did not properly handle certain malformed messages in the MSN protocol handler. A remote attacker could send a specially crafted message and possibly execute arbitrary code with user privileges.
 
Ubuntu: Apache regression  19 August 2009 
Posted by Benjamin D. Thomas   
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. We apologize for the inconvenience. Original advisory details: It was discovered that mod_proxy_http did not properly handle a large amount of streamed data when used as a reverse proxy. A remote attacker could exploit this and cause a denial of service via memory resource consumption. This issue affected Ubuntu 8.04 LTS, 8.10 and 9.04. (CVE-2009-1890) It was discovered that mod_deflate did not abort compressing large files when the connection was closed. A remote attacker could exploit this and cause a denial of service via CPU resource consumption. (CVE-2009-1891)
 
Ubuntu: libxml2 vulnerabilities  11 August 2009 
Posted by Benjamin D. Thomas   
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. (CVE-2009-2414) It was discovered that libxml2 did not correctly parse Notation and Enumeration attribute types. 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. (CVE-2009-2416) USN-644-1 fixed a vulnerability in libxml2. This advisory provides the corresponding update for Ubuntu 9.04. Original advisory details: It was discovered that libxml2 did not correctly handle long entity names. If a user were tricked into processing a specially crafted XML document, a remote attacker could execute arbitrary code with user privileges or cause the application linked against libxml2 to crash, leading to a denial of service. (CVE-2008-3529)
