A vulnerability classified as critical has been found in OpenSSL up to 1.0.2h (Network Encryption Software). Affected is the function TS_OBJ_print_bio
in the library crypto/ts/ts_lib.c of the component X.509 Public Key Infrastructure Time-Stamp Protocol Handler. The manipulation of the argument timestamp
with an unknown input leads to a out-of-bounds vulnerability. CWE is classifying the issue as CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. This is going to have an impact on availability. CVE summarizes:
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 through 1.0.2h allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted time-stamp file that is mishandled by the "openssl ts" command.
The weakness was released 08/01/2016 by Shi Lei as USN-3087-1 (Website). The advisory is shared for download at kb.juniper.net. This vulnerability is traded as CVE-2016-2180 since 01/29/2016.
