Ubuntu: Squid vulnerability  09 January 2008 
Posted by Benjamin D. Thomas   
It was discovered that Squid did not always clean up cache memory correctly. A remote attacker could manipulate cache update replies and cause Squid to use all available memory, leading to a denial of service.
 
Ubuntu: Net-SNMP vulnerability  09 January 2008 
Posted by Benjamin D. Thomas   
Bill Trost discovered that snmpd did not properly limit GETBULK requests. A remote attacker could specify a large number of max-repetitions and cause a denial of service via resource exhaustion.
 
Ubuntu: CUPS vulnerabilities  09 January 2008 
Posted by Benjamin D. Thomas   
Wei Wang discovered that the SNMP discovery backend did not correctly calculate the length of strings. If a user were tricked into scanning for printers, a remote attacker could send a specially crafted packet and possibly execute arbitrary code.
 
Ubuntu: pwlib vulnerability  09 January 2008 
Posted by Benjamin D. Thomas   
Jose Miguel Esparza discovered that pwlib did not correctly handle large string lengths. A remote attacker could send specially crafted packets to applications linked against pwlib (e.g. Ekiga) causing them to crash, leading to a denial of service.
 
Ubuntu: opal vulnerability  09 January 2008 
Posted by Benjamin D. Thomas   
Jose Miguel Esparza discovered that certain SIP headers were not correctly validated. A remote attacker could send a specially crafted packet to an application linked against opal (e.g. Ekiga) causing it to crash, leading to a denial of service.
 
Ubuntu: Tomboy vulnerability  07 January 2008 
Posted by Benjamin D. Thomas   
Jan Oravec discovered that Tomboy did not properly setup the LD_LIBRARY_PATH environment variable. A local attacker could exploit this to execute arbitrary code as the user invoking the program.
 
Ubuntu: Linux kernel vulnerabilities  18 December 2007 
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) Certain calculations in the hugetlb code were not correct. A local attacker could exploit this to cause a kernel panic, leading to a denial of service.
