Remote Snort Back Orifice preprocessor overflow Metasploit exploit for Win32 targets. Exploits Snort versions 2.4.0 through 2.4.2. Tested against Snort 2.4.2 Binary with Windows XP Professional SP1/SP2, Windows Server 2003 SP1, Windows Server 2000 SP0, and Windows 2000 Professional SP0.

With Windows 2000 Microsoft introduced the inheritance of access rights and new Win32-API functions like SetNamedSecurityInfo() which handle the inheritance. SetNamedSecurityInfo() but has a serious bug: it applies inheritable ACEs from a PARENT object to a target object even if it must not do so, indicated by the flags SE_DACL_PROTECTED and/or SE_SACL_PROTECTED in the security descriptor of the target object.

Ubuntu Security Notice 4171-5 - USN-4171-1 fixed vulnerabilities in Apport. This caused a regression in autopkgtest and python2 compatibility. This update fixes the problem.

Stegano is a basic Python Steganography module. Stegano implements two methods of hiding: using the red portion of a pixel to hide ASCII messages, and using the Least Significant Bit (LSB) technique. It is possible to use a more advanced LSB method based on integers sets. The sets (Sieve of Eratosthenes, Fermat, Carmichael numbers, etc.) are used to select the pixels used to hide the information.
