CVE-2016-2180

39
FAUCET Score

CVE-2016-2180 is an out-of-bounds read vulnerability in the TS_OBJ_print_bio function of OpenSSL's X.509 Time-Stamp Protocol (TSP) implementation, affecting OpenSSL versions up to 1.0.2h, including various Linux distributions. This flaw allows remote attackers to trigger a denial of service (application crash) by providing a specially crafted time-stamp file to the "openssl ts" command. Rated with a CVSS score of 7.5 (High), it is easily exploitable over the network with low attack complexity and no user interaction required, leading to high availability impact. Despite its severity, there is no evidence of active exploitation, public exploit code, or significant community discussion or media coverage, suggesting it is not currently a high-profile threat.
