A 20 year old critical subtle integer overflow vulnerability has been discovered in Lempel-Ziv-Oberhumer (LZO), an extremely efficient data compression algorithm that focuses on decompression speed. The vulnerability in the algorithm could trigger buffer overflows, denial of service and remote code execution. LZO/LZ4 algorithm is also used in some car and aircraft systems, as well as NASA’s Rover,, which is right now on planet Mars and has completed its first year this week.
