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.
 
Ubuntu: Qt vulnerability  21 February 2008 
Posted by Benjamin D. Thomas   
It was discovered that QSslSocket did not properly verify SSL certificates. A remote attacker may be able to trick applications using QSslSocket into accepting invalid SSL certificates.
 
Ubuntu: Linux kernel vulnerabilities  13 February 2008 
Posted by Benjamin D. Thomas   
The minix filesystem did not properly validate certain filesystem values. If a local attacker could trick the system into attempting to mount a corrupted minix filesystem, the kernel could be made to hang for long periods of time, resulting in a denial of service. (CVE-2006-6058)
 
Ubuntu: Linux kernel vulnerability  12 February 2008 
Posted by Benjamin D. Thomas   
Wojciech Purczynski discovered that the vmsplice system call did not properly perform verification of user-memory pointers. A local attacker could exploit this to overwrite arbitrary kernel memory and gain root privileges. (CVE-2008-0600)
