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.
 
Ubuntu: Perl vulnerability  02 July 2009 
Posted by Benjamin D. Thomas   
It was discovered that the Compress::Raw::Zlib Perl module incorrectly handled certain zlib compressed streams. If a user or automated system were tricked into processing a specially crafted compressed stream or file, a remote attacker could crash the application, leading to a denial of service.
 
Ubuntu: Nagios vulnerability  02 July 2009 
Posted by Benjamin D. Thomas   
It was discovered that Nagios did not properly parse certain commands submitted using the WAP web interface. An authenticated user could exploit this flaw and execute arbitrary programs on the server.
 
Ubuntu: OpenSSL vulnerabilities  25 June 2009 
Posted by Benjamin D. Thomas   
It was discovered that OpenSSL did not limit the number of DTLS records it would buffer when they arrived with a future epoch. A remote attacker could cause a denial of service via memory resource consumption by sending a large number of crafted requests. (CVE-2009-1377) It was discovered that OpenSSL did not properly free memory when processing DTLS fragments. A remote attacker could cause a denial of service via memory resource consumption by sending a large number of crafted requests. (CVE-2009-1378) It was discovered that OpenSSL did not properly handle certain server certificates when processing DTLS packets. A remote DTLS server could cause a denial of service by sending a message containing a specially crafted server certificate. (CVE-2009-1379) It was discovered that OpenSSL did not properly handle a DTLS ChangeCipherSpec packet when it occured before ClientHello. A remote attacker could cause a denial of service by sending a specially crafted request. (CVE-2009-1386) It was discovered that OpenSSL did not properly handle out of sequence DTLS handshake messages. A remote attacker could cause a denial of service by sending a specially crafted request. (CVE-2009-1387)
