SAP LZC/LZH Compression Denial Of Service
Posted May 13, 2015
Authored by Core Security Technologies, Martin Gallo | Site coresecurity.com

Core Security Technologies Advisory - SAP products make use of a proprietary implementation of the Lempel-Ziv-Thomas (LZC) adaptive dictionary compression algorithm and the Lempel-Ziv-Huffman (LZH) compression algorithm. These compression algorithms are used across several SAP products and programs. Vulnerabilities were found in the decompression routines that could be triggered in different scenarios, and could lead to execution of arbitrary code and denial of service conditions.
