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.
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)
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)
Various flaws were discovered in the browser and JavaScript engine. By tricking a user into opening a malicious web page, an attacker could execute arbitrary code with the user's privileges. (CVE-2008-0412, CVE-2008-0413)
It was discovered that Apache did not sanitize the Expect header from an HTTP request when it is reflected back in an error message, which could result in browsers becoming vulnerable to cross-site scripting attacks when processing the output. With cross-site scripting vulnerabilities, if a user were tricked into viewing server 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. This was only vulnerable in Ubuntu 6.06. (CVE-2006-3918)
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. This was only vulnerable in Ubuntu 7.04 and 7.10. (CVE-2006-6058)
It was discovered that PulseAudio did not properly drop privileges when running as a daemon. Local users may be able to exploit this and gain privileges. The default Ubuntu configuration is not affected.
Multiple overflows were discovered in the XFree86-Misc, XInput-Misc, TOG-CUP, EVI, and MIT-SHM extensions which did not correctly validate function arguments. An authenticated attacker could send specially crafted requests and gain root privileges. (CVE-2007-5760, CVE-2007-6427, CVE-2007-6428, CVE-2007-6429)
Felipe Sateler discovered that apt-listchanges did not use safe paths when importing additional Python libraries. A local attacker could exploit this and execute arbitrary commands as the user running apt-listchanges.
Multiple overflows were discovered in the XFree86-Misc, XInput-Misc, TOG-CUP, EVI, and MIT-SHM extensions which did not correctly validate function arguments. An authenticated attacker could send specially crafted requests and gain root privileges.
Will Drewry and Tavis Ormandy discovered that the boost library did not properly perform input validation on regular expressions. An attacker could send a specially crafted regular expression to an application linked against boost and cause a denial of service via application crash.
Brad Fitzpatrick discovered that libxml2 did not correctly handle certain UTF-8 sequences. If a remote attacker were able to trick a user or automated system into processing a specially crafted XML document, the application linked against libxml2 could enter an infinite loop, leading to a denial of service via CPU resource consumption.
Nico Leidecker discovered that PostgreSQL did not properly restrict dblink functions. An authenticated user could exploit this flaw to access arbitrary accounts and execute arbitrary SQL queries. (CVE-2007-3278, CVE-2007-6601)
It was discovered that in very rare configurations using LDAP, Dovecot may reuse cached connections for users with the same password. As a result, a user may be able to login as another if the connection is reused. The default Ubuntu configuration of Dovecot was not vulnerable.
Jan Pechanec discovered that ssh would forward trusted X11 cookies when untrusted cookie generation failed. This could lead to unintended privileges being forwarded to a remote host.
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.
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.
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.
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.
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.
