Ubuntu: tar vulnerability  28 August 2007 
Posted by Benjamin D. Thomas   
Dmitry V. Levin discovered that tar did not correctly detect the ".." file path element when unpacking archives. If a user or an automated system were tricked into unpacking a specially crafted tar file, arbitrary files could be overwritten with user privileges.
Ubuntu: vim vulnerability  28 August 2007 
Posted by Benjamin D. Thomas   
Ulf Harnhammar discovered that vim does not properly sanitise the "helptags_one()" function when running the "helptags" command. By tricking a user into running a crafted help file, a remote attacker could execute arbitrary code with the user's privileges.
Ubuntu: KDE vulnerabilities  27 August 2007 
Posted by Benjamin D. Thomas   
It was discovered that Konqueror could be tricked into displaying incorrect URLs. Remote attackers could exploit this to increase their chances of tricking a user into visiting a phishing URL, which could lead to credential theft.
Ubuntu: Thunderbird vulnerabilities  27 August 2007 
Posted by Benjamin D. Thomas   
Various flaws were discovered in the layout and JavaScript engines. By tricking a user into opening a malicious email, an attacker could execute arbitrary code with the user's privileges. Please note that JavaScript is disabled by default for emails, and it is not recommended to enable it.
Ubuntu: jasper vulnerability  21 August 2007 
Posted by Benjamin D. Thomas   
It was discovered that Jasper did not correctly handle corrupted JPEG2000 images. By tricking a user into opening a specially crafted JPG, a remote attacker could cause the application using libjasper to crash, resulting in a denial of service.
Ubuntu: rsync vulnerability  20 August 2007 
Posted by Benjamin D. Thomas   
Sebastian Krahmer discovered that rsync contained an off-by-one miscalculation when handling certain file paths. By creating a specially crafted tree of files and tricking an rsync server into processing them, a remote attacker could write a single NULL to stack memory, possibly leading to arbitrary code execution.
Ubuntu: Apache vulnerabilities  20 August 2007 
Posted by Benjamin D. Thomas   
Stefan Esser discovered that mod_status did not force a character set, which could result in browsers becoming vulnerable to XSS attacks when processing the output. If a user were tricked into viewing server status output during a crafted server request, a remote attacker could exploit this to modify the contents, or steal confidential data (such as passwords), within the same domain. By default, mod_status is disabled in Ubuntu.
