Debian DSA-145-1 : tinyproxy - doubly freed memory

The authors of tinyproxy, a lightweight HTTP proxy, discovered a bug in the handling of some invalid proxy requests. Under some circumstances, an invalid request may result in allocated memory being freed twice. This can potentially result in the execution of arbitrary code. %NASLMINLEVEL 70300 C...

SuSE-SA:2004:005: Linux Kernel

The remote host is missing the patch for the advisory SuSE-SA:2004:005 Linux Kernel. Another bug in the Kernel's domremap function, which is unrelated to the bug fixed in SuSE-SA:2004:001, was found by Paul Starzetz. The domremap function of the Linux Kernel is used to manage Virtual Memory Areas...
