Ubuntu: libicu vulnerabilities  24 March 2008 
Posted by Benjamin D. Thomas   
Will Drewry discovered that libicu did not properly handle '\0' when processing regular expressions. If an application linked against libicu processed a crafted regular expression, an attacker could execute arbitrary code with privileges of the user invoking the program.
Ubuntu: unzip vulnerability  20 March 2008 
Posted by Benjamin D. Thomas   
Tavis Ormandy discovered that unzip did not correctly clean up pointers. If a user or automated service was tricked into processing a specially crafted ZIP archive, a remote attacker could execute arbitrary code with user privileges.
Ubuntu: MySQL vulnerabilities  20 March 2008 
Posted by Benjamin D. Thomas   
Masaaki Hirose discovered that MySQL could be made to dereference a NULL pointer. An authenticated user could cause a denial of service (application crash) via an EXPLAIN SELECT FROM on the INFORMATION_SCHEMA table. This issue only affects Ubuntu 6.06 and 6.10. (CVE-2006-7232) Alexander Nozdrin discovered that MySQL did not restore database access privileges when returning from SQL SECURITY INVOKER stored routines. An authenticated user could exploit this to gain privileges. This issue does not affect Ubuntu 7.10. (CVE-2007-2692)
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.
