CVE-2016-1576

CVE-2016-1576 concerns the Linux kernel overlayfs. The overlayfs implementation up to version 4.5.2 does not properly restrict the mount namespace, enabling a local user to gain privileges by mounting an overlay filesystem on top of a FUSE filesystem and then executing a crafted setuid program. T...

CVE-2015-4176

fs/namespace.c in the Linux kernel before 4.0.2 does not properly support mount connectivity, which allows local users to read arbitrary files by leveraging user-namespace root access for deletion of a file or directory...

CVE-2016-2853

CVE-2016-2853 – Linux kernel aufs Privilege Escalation : The vulnerability arises in the aufs module (Linux kernel 3.x/4.x) where mount namespace restrictions are insufficient.

GitLab: GFM renderer leaks external issue tracker URL of private project

Vulnerability details The GFM renderer has the ability to cross-link issues between projects. When this project is private and the user doesn't have access, the link isn't made. This is good. However, when the private project has an external issue tracker set up, an attacker can extract the...
