Vulnerability identifier: #VU41410

Vulnerability risk: Medium

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CWE-ID: CWE-200

Exploitation vector: Network

Exploit availability: No

Vulnerable software:
OpenSSL

Vendor: OpenSSL Software Foundation

Description

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

The OBJ_obj2txt function in crypto/objects/obj_dat.c in OpenSSL 0.9.8 before 0.9.8zb, 1.0.0 before 1.0.0n, and 1.0.1 before 1.0.1i, when pretty printing is used, does not ensure the presence of '' characters, which allows context-dependent attackers to obtain sensitive information from process stack memory by reading output from X509_name_oneline, X509_name_print_ex, and unspecified other functions.

Mitigation
Install update from vendor's website.

Vulnerable software versions

OpenSSL: 0.9.8 - 0.9.8za, 1.0.0 - 1.0.0m, 1.0.1 - 1.0.1h
