Ubuntu: Kerberos vulnerabilities  19 March 2008 
Posted by Benjamin D. Thomas   
It was discovered that krb5 did not correctly handle certain krb4 requests. An unauthenticated remote attacker could exploit this flaw by sending a specially crafted traffic, which could expose sensitive information, cause a crash, or execute arbitrary code. (CVE-2008-0062, CVE-2008-0063)
 
Ubuntu: mailman vulnerability  15 March 2008 
Posted by Benjamin D. Thomas   
Multiple cross-site scripting flaws were discovered in mailman. A malicious list administrator could exploit this to execute arbitrary JavaScript, potentially stealing user credentials.
 
Ubuntu: Python vulnerabilities  10 March 2008 
Posted by Benjamin D. Thomas   
Piotr Engelking discovered that strxfrm in Python was not correctly calculating the size of the destination buffer. This could lead to small information leaks, which might be used by attackers to gain additional knowledge about the state of a running Python script. (CVE-2007-2052) A flaw was discovered in the Python imageop module. If a script using the module could be tricked into processing a specially crafted set of arguments, a remote attacker could execute arbitrary code, or cause the application to crash. (CVE-2007-4965)
 
Ubuntu: Thunderbird vulnerabilities  06 March 2008 
Posted by Benjamin D. Thomas   
USN-582-1 fixed several vulnerabilities in Thunderbird. The upstream fixes were incomplete, and after performing certain actions Thunderbird would crash due to memory errors. This update fixes the problem. We apologize for the inconvenience.
 
Ubuntu: OpenLDAP vulnerabilities  05 March 2008 
Posted by Benjamin D. Thomas   
Jonathan Clarke discovered that the OpenLDAP slapd server did not properly handle modify requests when using the Berkeley DB backend and the NOOP control was used. An authenticated user with modify permissions could send a crafted modify request and cause a denial of service via application crash. Ubuntu 7.10 is not affected by this issue. (CVE-2007-6698)
 
Ubuntu: Evolution vulnerability  05 March 2008 
Posted by Benjamin D. Thomas   
Ulf Harnhammar discovered that Evolution did not correctly handle format strings when processing encrypted emails. A remote attacker could exploit this by sending a specially crafted email, resulting in arbitrary code execution.
 
Ubuntu: Thunderbird vulnerabilities  29 February 2008 
Posted by Benjamin D. Thomas   
It was discovered that Thunderbird did not properly set the size of a buffer when parsing an external-body MIME-type. If a user were to open a specially crafted email, an attacker could cause a denial of service via application crash or possibly execute arbitrary code as the user.
