DATE CVE VULNERABILITY TITLE RISK
2008-04-18 CVE-2008-1887 Classic Buffer Overflow vulnerability in multiple products
Python 2.5.2 and earlier allows context-dependent attackers to execute arbitrary code via multiple vectors that cause a negative size value to be provided to the PyString_FromStringAndSize function, which allocates less memory than expected when assert() is disabled and triggers a buffer overflow.

2008-03-19 CVE-2008-0062 Improper Initialization vulnerability in multiple products
KDC in MIT Kerberos 5 (krb5kdc) does not set a global variable for some krb4 message types, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted messages that trigger a NULL pointer dereference or double-free.

2008-01-18 CVE-2007-6427 Out-Of-Bounds Write vulnerability in multiple products
The XInput extension in X.Org Xserver before 1.4.1 allows context-dependent attackers to execute arbitrary code via requests related to byte swapping and heap corruption within multiple functions, a different vulnerability than CVE-2007-4990.

2007-09-18 CVE-2007-2834 Integer Overflow or Wraparound vulnerability in multiple products
Integer overflow in the TIFF parser in OpenOffice.org (OOo) before 2.3; and Sun StarOffice 6, 7, and 8 Office Suite (StarSuite); allows remote attackers to execute arbitrary code via a TIFF file with crafted values of unspecified length fields, which triggers allocation of an incorrect amount of memory, resulting in a heap-based buffer overflow.
