UNKNOWN Summary
Buffer overflow in programs/pluto/xauth.c in the client in Openswan 2.6.25 through 2.6.28 might allow remote authenticated gateways to execute arbitrary code or cause a denial of service via long (1) cisco_dns_info or (2) cisco_domain_info data in a packet.

Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

NASL family Oracle Linux Local Security Checks NASL id ORACLELINUX_ELSA-2010-0892.NASL description From Red Hat Security Advisory 2010:0892 : Updated openswan packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. Openswan is a free implementation of Internet Protocol Security (IPsec) and Internet Key Exchange (IKE). IPsec uses strong cryptography to provide both authentication and encryption services. These services allow you to build secure tunnels through untrusted networks. Two buffer overflow flaws were found in the Openswan client-side XAUTH handling code used when connecting to certain Cisco gateways. A malicious or compromised VPN gateway could use these flaws to execute arbitrary code on the connecting Openswan client. (CVE-2010-3302, CVE-2010-3308) Two input sanitization flaws were found in the Openswan client-side handling of Cisco gateway banners. A malicious or compromised VPN gateway could use these flaws to execute arbitrary code on the connecting Openswan client. (CVE-2010-3752, CVE-2010-3753) Red Hat would like to thank the Openswan project for reporting these issues. Upstream acknowledges D. Hugh Redelmeier and Paul Wouters as the original reporters. All users of openswan are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, the ipsec service will be restarted automatically. last seen 2020-06-01 modified 2020-06-02 plugin id 68145 published 2013-07-12 reporter This script is Copyright (C) 2013-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/68145 title Oracle Linux 6 : openswan (ELSA-2010-0892) NASL family Fedora Local Security Checks NASL id FEDORA_2010-15516.NASL description - New upstream release - Fixes for CVE-2010-3308 and CVE-2010-3302 Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory.
