Arbitrary Code Execution

kernel-rt is vulnerable to arbitrary code execution attacks. The vulnerability exists as arch/x86/kvm/mmu.c in the Linux kernel through 4.13.5, when nested virtualisation is used, does not properly traverse guest pagetable entries to resolve a guest virtual address, which allows L1 guest OS users...

Denial Of Service (DoS)

gnome-vfs2 is vulnerable to denial of service DoS attacks. The vulnerability exists as neon before 0.28.6, when expat is used, does not properly detect recursion during entity expansion, which allows context-dependent attackers to cause a denial of service memory and CPU consumption via a crafted...
