Linux kernel pointer dereference vulnerability

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. A security vulnerability exists in the expanddownwards of the mm/mmap.c file in versions of Linux kernel prior to 4.20.14. An attacker can exploit this vulnerability t...

kernel: Use-after-free in the vmacache_flush_all function resulting in a possible privilege escalation

A security flaw was discovered in the Linux kernel. The vmacacheflushall function in mm/vmacache.c mishandles sequence number overflows. An attacker can trigger a use-after-free and possibly gain privileges via certain thread creation, map, unmap, invalidation, and dereference operations...

DEBIAN-CVE-2018-12896

An issue was discovered in the Linux kernel through 4.17.3. An Integer Overflow in kernel/time/posix-timers.c in the POSIX timer code is caused by the way the overrun accounting works. Depending on interval and expiry time values, the overrun can be larger than INTMAX, but the accounting is int...

UBUNTU-CVE-2018-12714

An issue was discovered in the Linux kernel through 4.17.2. The filter parsing in kernel/trace/traceeventsfilter.c could be called with no filter, which is an N=0 case when it expected at least one line to have been read, thus making the N-1 index invalid. This allows attackers to cause a denial ...

Debugging Complex Malware that Executes Code on the Heap

Introduction In this blog, I will share a simple debugging tactic for creating “save points” during iterative remote debugging of complex multi-stage samples that execute code in heap memory at non-deterministic addresses. I’ll share two examples: one contrived, and the other a complex, modular...
