CVE-2016-2854

CVE-2016-2854 concerns the AUFS module in the Linux kernel (versions 3.x/4.x), which does not properly maintain POSIX ACL xattr data. This can allow a local attacker to gain privileges by exploiting a group-writable setgid directory. The connected documents confirm the vulnerability and its local...

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. A local attacker can mount an aufs filesystem atop a FUSE filesystem and, by executing a crafted setuid program, escalat...

Linux kernel competitive conditions vulnerability

The Linux kernel is the kernel used by the operating system Linux, released by the Linux Foundation in the United States. A competitive condition vulnerability exists in the Advanced Union Filesystem aufs aufs3-mmap.patch and aufs4-mmap.patch patches for Linux kernel versions 3.x and 4.x. The...

DEBIAN-CVE-2015-7312

Multiple race conditions in the Advanced Union Filesystem aufs aufs3-mmap.patch and aufs4-mmap.patch patches for the Linux kernel 3.x and 4.x allow local users to cause a denial of service use-after-free and BUG or possibly gain privileges via a 1 madvise or 2 msync system call, related to...

CVE-2015-7312

CVE-2015-7312 affects the Linux kernel 3.x/4.x via race conditions in the aufs aufs3-mmap.patch and aufs4-mmap.patch patches. The vulnerability allows local users to cause denial of service (use-after-free/BUG) or potentially gain privileges through madvise or msync calls, related to mm/madvise.c...
