The vulnerability of the glibc implementation library, which allows attackers to increase their privileges

The vulnerability of the ptchown function in the glibc execution library arises from the lack of namespace checking related to the file descriptor passed as an argument. Exploiting this vulnerability allows a local attacker to record keyboard input, replace data, or potentially increase their...

Firefox Add-On Flaw Leaves Apple And Windows Computers Open To Attack

Researchers warn hundreds of popular Firefox browser extensions are vulnerable to attack that could give hackers control of Mac OS X and Windows computers. Researchers from Northeastern University say the flaw is tied to Firefox’s support for an older browser extension platform and the Mozilla...

jre8-openjdk: sandbox escape

It was discovered that the security fix for CVE-2013-5838 was incomplete and still allowed remote attackers to escape the Java security sandbox mechanism. The root problem is that the Reflection API does not properly guarantee type safety when Method Handle objects were invoked across two differe...

Linux kernel elevation of privilege vulnerability (CNVD-2016-01042)

The Linux kernel is an open source, free operating system kernel originally done by Linus Torvalds. A security vulnerability exists in the kernel/ptrace.c file in Linux kernel 4.4.1 and earlier versions, which stems from the program's failure to properly handle uid and gid mappings. A local...

Medium: kernel

Issue Overview: The Linux kernel before 4.4.1 allows local users to bypass file-descriptor limits and cause a denial of service memory consumption by sending each descriptor over a UNIX socket before closing it, related to net/unix/afunix.c and net/unix/garbage.c. CVE-2013-4312 A race condition i...
