PARTIAL Summary

Vulnerable Configurations
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.

This issue only caused a temporary denial of service, as mysqld was automatically restarted after the crash. (CVE-2012-2102) This update also adds the following enhancement : * The InnoDB storage engine is built-in for all architectures. This update adds InnoDB Plugin, the InnoDB storage engine as a plug-in for the 32-bit x86, AMD64, and Intel 64 architectures. The plug-in offers additional features and better performance than when using the built-in InnoDB storage engine. Refer to the MySQL documentation, linked to in the References section, for information about enabling the plug-in. (BZ#740224) All MySQL users should upgrade to these updated packages, which add this enhancement and contain a backported patch to correct this issue.

There are several known incompatible changes, which are listed in /usr/share/doc/mysql-server/NEWS.Debian.gz. Several issues have been discovered in the MySQL database server. The vulnerabilities are addressed by upgrading MySQL to a new upstream version, 5.1.63, which includes additional changes, such as performance improvements and corrections for data loss defects. These changes are described in the MySQL release notes. CVE-2012-2122, an authentication bypass vulnerability, occurs only when MySQL has been built in with certain optimisations enabled. The packages in Debian stable (squeeze) are not known to be affected by this vulnerability. It is addressed in this update nonetheless, so future rebuilds will not become vulnerable to this issue. last seen 2020-03-17 modified 2012-06-29 plugin id 59774 published 2012-06-29 reporter This script is Copyright (C) 2012-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/59774 title Debian DSA-2496-1 : mysql-5.1 - several vulnerabilities NASL family Databases NASL id MYSQL_5_5_22.NASL description The version of MySQL 5.5 installed on the remote host is earlier than 5.5.22.
