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.
 
Ubuntu: PCRE vulnerability  21 February 2008 
Posted by Benjamin D. Thomas   
It was discovered that PCRE did not correctly handle very long strings containing UTF8 sequences. In certain situations, an attacker could exploit applications linked against PCRE by tricking a user or automated system in processing a malicious regular expression leading to a denial of service or possibly arbitrary code execution.
 
Ubuntu: libcdio vulnerability  21 February 2008 
Posted by Benjamin D. Thomas   
Devon Miller discovered that the iso-info and cd-info tools did not properly perform bounds checking. If a user were tricked into using these tools with a crafted iso image, an attacker could cause a denial of service via a core dump, and possibly execute arbitrary code.
