Out-of-bounds read in OpenSSL - CVE-2016-2180

Vulnerability identifier: #VU308

CSH Severity: Medium

CVSS v4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2016-2180

CWE-ID: CWE-125

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary condition within the TS_OBJ_print_bio() function in crypto/ts/ts_lib.c in the X.509 Public Key Infrastructure Time-Stamp Protocol (TSP) implementation in OpenSSL. A remote attacker can perform a denial of service (DoS) attack via a crafted time-stamp file that is mishandled by the "openssl ts" command.
