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...
