Vulnerability identifier: #VU41410
Vulnerability risk: Medium
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID:
CWE-ID:
CWE-200
Exploitation vector: Network
Exploit availability: No
Vulnerable software:
OpenSSL

Encryption software
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: 0.9.8y - 0.9.8p, 1.0.0g - 1.0.0, 1.0.1c - 1.0.1
