NASL family Mandriva Local Security Checks NASL id MANDRAKE_MDKSA-2005-096.NASL description Colin Percival reported a cache timing attack that could be used to allow a malicious local user to gain portions of cryptographic keys (CVE-2005-0109). The OpenSSL library has been patched to add a new fixed-window mod_exp implementation as default for RSA, DSA, and DH private key operations. The patch was designed to mitigate cache timing and possibly related attacks. last seen 2020-06-01 modified 2020-06-02 plugin id 18434 published 2005-06-08 reporter This script is Copyright (C) 2005-2019 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/18434 title Mandrake Linux Security Advisory : openssl (MDKSA-2005:096) code #%NASL_MIN_LEVEL 80502 # # (C) Tenable Network Security, Inc. # # The descriptive text and package checks in this plugin were # extracted from Mandrake Linux Security Advisory MDKSA-2005:096. # The text itself is copyright (C) Mandriva S.A. # include("compat.inc"); if (description) { script_id(18434); script_version ("1.17"); script_cvs_date("Date: 2019/08/02 13:32:47"); script_cve_id("CVE-2005-0109"); script_xref(name:"MDKSA", value:"2005:096"); script_name(english:"Mandrake Linux Security Advisory : openssl (MDKSA-2005:096)"); script_summary(english:"Checks rpm output for the updated packages"); script_set_attribute( attribute:"synopsis", value: "The remote Mandrake Linux host is missing one or more security updates." ); script_set_attribute( attribute:"description", value: "Colin Percival reported a cache timing attack that could be used to allow a malicious local user to gain portions of cryptographic keys (CVE-2005-0109).

This update has been rated as having moderate security impact by the Red Hat Security Response Team. OpenSSL is a toolkit that implements Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as a full-strength general purpose cryptography library. Colin Percival reported a cache timing attack that could allow a malicious local user to gain portions of cryptographic keys. The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CVE-2005-0109 to the issue. The OpenSSL library has been patched to add a new fixed-window mod_exp implementation as default for RSA, DSA, and DH private-key operations. This patch is designed to mitigate cache timing and potentially related attacks. A flaw was found in the way the der_chop script creates temporary files. It is possible that a malicious local user could cause der_chop to overwrite files (CVE-2004-0975). The der_chop script was deprecated and has been removed from these updated packages. Red Hat Enterprise Linux 4 did not ship der_chop and is therefore not vulnerable to this issue. Users are advised to update to these erratum packages which contain patches to correct these issues. Please note: After installing this update, users are advised to either restart all services that use OpenSSL or restart their system. last seen 2020-06-01 modified 2020-06-02 plugin id 21830 published 2006-07-03 reporter This script is Copyright (C) 2006-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/21830 title CentOS 3 / 4 : openssl (CESA-2005:476) NASL family Mandriva Local Security Checks NASL id MANDRAKE_MDKSA-2005-111.NASL description Multiple vulnerabilities in the Linux kernel have been discovered and fixed in this update.
