Title: libxml2 vulnerabilities
Summary: Several security issues were fixed in libxml2.
It was discovered that libxml2 incorrectly handled certain malformed
documents. If a user or automated system were tricked into opening a
specially crafted document, an attacker could possibly cause libxml2 to
crash, resulting in a denial of service. (CVE-2015-8806, CVE-2016-2073,

CVE-2000-1134 [HIGH] namei: allow restricted O_CREAT of FIFOs and regular files
namei: allow restricted O_CREAT of FIFOs and regular files
Disallows open of FIFOs or regular files not owned by the user in world
writable sticky directories, unless the owner is the same as that of the
directory or the file is opened without the O_CREAT flag. The purpose
is to make data spoofing attacks harder. This protection can be turned
on and off separately for FIFOs and regular files via sysctl, just like
the symlinks/hardlinks protection. This patch is based on Openwall's
"HARDEN_FIFO" feature by Solar Designer.

### Abstract
In software development, the prevalence of unsafe languages such as C and C++ introduces potential vulnerabilities, especially within the heap, a pivotal component for dynamic memory allocation. Despite its significance, heap management complexities have made heap corruption pervasive, posing severe threats to system security. While prior solutions aiming for temporal and spatial memory safety exhibit overheads deemed impractical, we present , a unique heap memory protection design. At its core, is an efficient out-of-bounds defe
