Ubuntu: PostgreSQL vulnerability  07 April 2009 
Posted by Benjamin D. Thomas   
It was discovered that PostgreSQL did not properly handle encoding conversion failures. An attacker could exploit this by sending specially crafted requests to PostgreSQL, leading to a denial of service.
 
Ubuntu: libsndfile vulnerability  30 March 2009 
Posted by Benjamin D. Thomas   
It was discovered that libsndfile did not correctly handle description chunks in CAF audio files. If a user or automated system were tricked into opening a specially crafted CAF audio file, an attacker could execute arbitrary code with the privileges of the user invoking the program.
 
Ubuntu: ICU vulnerability  26 March 2009 
Posted by Benjamin D. Thomas   
It was discovered that libicu did not correctly handle certain invalid encoded data. If a user or automated system were tricked into processing specially crafted data with applications linked against libicu, certain content filters could be bypassed.
 
Ubuntu: xine-lib vulnerability  26 March 2009 
Posted by Benjamin D. Thomas   
It was discovered that the 4xm demuxer in xine-lib did not correctly handle a large current_track value in a 4xm file, resulting in an integer overflow. If a user or automated system were tricked into opening a specially crafted 4xm movie file, an attacker could crash xine-lib or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2009-0698)
 
Ubuntu: Ghostscript vulnerabilities  23 March 2009 
Posted by Benjamin D. Thomas   
It was discovered that Ghostscript contained multiple integer overflows in its ICC color management library. If a user or automated system were tricked into opening a crafted Postscript file, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program. (CVE-2009-0583) It was discovered that Ghostscript did not properly perform bounds checking in its ICC color management library. If a user or automated system were tricked into opening a crafted Postscript file, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program. (CVE-2009-0584)
 
Ubuntu: LittleCMS vulnerabilities  23 March 2009 
Posted by Benjamin D. Thomas   
Chris Evans discovered that LittleCMS did not properly handle certain error conditions, resulting in a large memory leak. If a user or automated system were tricked into processing an image with malicious ICC tags, a remote attacker could cause a denial of service. (CVE-2009-0581) Chris Evans discovered that LittleCMS contained multiple integer overflows. If a user or automated system were tricked into processing an image with malicious ICC tags, a remote attacker could crash applications linked against liblcms1, leading to a denial of service, or possibly execute arbitrary code with user privileges. (CVE-2009-0723) Chris Evans discovered that LittleCMS did not properly perform bounds checking, leading to a buffer overflow. If a user or automated system were tricked into processing an image with malicious ICC tags, a remote attacker could execute arbitrary code with user privileges. (CVE-2009-0733)
 
Ubuntu: JasPer vulnerabilities  19 March 2009 
Posted by Benjamin D. Thomas   
It was discovered that JasPer did not correctly handle memory allocation when parsing certain malformed JPEG2000 images. If a user were tricked into opening a specially crafted image with an application that uses libjasper, an attacker could cause a denial of service and possibly execute arbitrary code with the user's privileges. (CVE-2008-3520) It was discovered that JasPer created temporary files in an insecure way. Local users could exploit a race condition and cause a denial of service in libjasper applications. (CVE-2008-3521) It was discovered that JasPer did not correctly handle certain formatting operations. If a user were tricked into opening a specially crafted image with an application that uses libjasper, an attacker could cause a denial of service and possibly execute arbitrary code with the user's privileges. (CVE-2008-3522)
