Ubuntu: NSPR update  04 August 2009 
Posted by Benjamin D. Thomas   
USN-810-1 fixed vulnerabilities in NSS. This update provides the NSPR needed to use the new NSS. Original advisory details: Moxie Marlinspike discovered that NSS did not properly handle regular expressions in certificate names. A remote attacker could create a specially crafted certificate to cause a denial of service (via application crash) or execute arbitrary code as the user invoking the program. (CVE-2009-2404) Moxie Marlinspike and Dan Kaminsky independently discovered that NSS did not properly handle certificates with NULL characters in the certificate name. An attacker could exploit this to perform a man in the middle attack to view sensitive information or alter encrypted communications. (CVE-2009-2408) Dan Kaminsky discovered NSS would still accept certificates with MD2 hash signatures. As a result, an attacker could potentially create a malicious trusted certificate to impersonate another site. (CVE-2009-2409)
 
Ubuntu: Python vulnerabilities  23 July 2009 
Posted by Benjamin D. Thomas   
It was discovered that Python incorrectly handled certain arguments in the imageop module. If an attacker were able to pass specially crafted arguments through the crop function, they could execute arbitrary code with user privileges. For Python 2.5, this issue only affected Ubuntu 8.04 LTS. (CVE-2008-4864) Multiple integer overflows were discovered in Python's stringobject and unicodeobject expandtabs method. If an attacker were able to exploit these flaws they could execute arbitrary code with user privileges or cause Python applications to crash, leading to a denial of service. (CVE-2008-5031)
 
Ubuntu: Ruby vulnerabilities  20 July 2009 
Posted by Benjamin D. Thomas   
It was discovered that Ruby did not properly validate certificates. An attacker could exploit this and present invalid or revoked X.509 certificates. (CVE-2009-0642) It was discovered that Ruby did not properly handle string arguments that represent large numbers. An attacker could exploit this and cause a denial of service. (CVE-2009-1904)
 
Ubuntu: D-Bus vulnerability  13 July 2009 
Posted by Benjamin D. Thomas   
It was discovered that the D-Bus library did not correctly validate signatures. If a local user sent a specially crafted D-Bus key, they could spoof a valid signature and bypass security policies.
 
Ubuntu: tiff vulnerability  13 July 2009 
Posted by Benjamin D. Thomas   
Tielei Wang and Tom Lane discovered that the TIFF library did not correctly handle certain malformed TIFF images. If a user or automated system were tricked into processing a malicious image, an attacker could execute arbitrary code with the privileges of the user invoking the program.
 
Ubuntu: Apache vulnerabilities  13 July 2009 
Posted by Benjamin D. Thomas   
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: tiff vulnerability  06 July 2009 
Posted by Benjamin D. Thomas   
It was discovered that the TIFF library did not correctly handle certain malformed TIFF images. If a user or automated system were tricked into processing a malicious image, a remote attacker could cause an application linked against libtiff to crash, leading to a denial of service.
