-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2008.0766 -- [Linux] Multiple vulnerabilities in Ingres Database for Linux 4 August 2008 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: Ingres Database Publisher: iDefense Operating System: Linux variants Impact: Root Compromise Execute Arbitrary Code/Commands Modify Arbitrary Files Access: Existing Account CVE Names: CVE-2008-3389 CVE-2008-3357 CVE-2008-3356 Original Bulletin: http://labs.idefense.com/intelligence/vulnerabilities/display.php?id=733 http://labs.idefense.com/intelligence/vulnerabilities/display.php?id=732 http://labs.idefense.com/intelligence/vulnerabilities/display.php?id=731 Comment: Note that there are three iDefense advisories in this bulletin. - --------------------------BEGIN INCLUDED TEXT-------------------- iDefense Security Advisory 08.01.08 http://labs.idefense.com/intelligence/vulnerabilities/ Aug 01, 2008 I. BACKGROUND Ingres Database is a database server used in several Computer Associates' products. For example, CA Directory Service uses the Ingres Database server. More information can be found on the vendor's website at the following URL. http://ingres.com/downloads/prod-cert-download.php II. DESCRIPTION Local exploitation of a file permissions modification vulnerability in the "verifydb" utility, as included with Ingres Database 2006 Release 2 for Linux, allows attackers to modify the permissions of files owned by the Ingres database user. The vulnerability exists within the "verifydb" utility included with Ingres. It is used to cleanup unneeded files created in the database directory. This program has the set-uid bit set, and is owned by the "ingres" user. The "verifydb" program improperly changes the permissions on files. The program first creates a file called "iivdb.log" in the current directory, and then makes it world writable. By creating a symbolic link to a file owned by the "ingres" user, an attacker can gain write access to the target file. III. ANALYSIS Exploitation of this vulnerability allows an attacker to overwrite arbitrary files owned by the "ingres" user. By itself, this vulnerability does not have very serious consequences. However, when combined with the library loading vulnerability, it allows an attacker to execute arbitrary code with root privileges. IV. DETECTION iDefense has confirmed the existence of this vulnerability in Ingres 2006 Enterprise Edition Release 2 for Linux x86 (32-bit). Other versions may also be affected. V. WORKAROUND iDefense is currently unaware of any workaround for this issue. VI. VENDOR RESPONSE "This problem has been identified and resolved by Ingres in the following releases: Ingres 2006 release 2 (9.1.0), Ingres 2006 release 1 (9.0.4), and Ingres 2.6." For more information, refer to Ingres' advisory at the following URL. http://www.ingres.com/support/security-alert-080108.php VII. CVE INFORMATION The Common Vulnerabilities and Exposures (CVE) project has assigned the name CVE-2008-3356 to this issue. This is a candidate for inclusion in the CVE list (http://cve.mitre.org/), which standardizes names for security problems. VIII. DISCLOSURE TIMELINE 07/20/2007 Initial vendor response 07/23/2007 Initial vendor notification 08/01/2008 Coordinated public disclosure IX.

BACKGROUND Ingres Database is a database server used in several Computer Associates' products. For example, CA Directory Service use thes Ingres Database server. More information can be found on the vendor's website at the following URL. http://ingres.com/downloads/prod-cert-download.php II. DESCRIPTION Local exploitation of a stack-based buffer overflow vulnerability in the "libbecompat" library, as included in Ingres Database 2006 Release 2 for Linux, allows attackers to execute arbitrary code with the privileges of the Ingres user. The vulnerability exists within the "libbecompat" library that is used by several of the set-uid "ingres" utilities included with Ingres. When copying a user supplied environment variable into a fixed-size stack buffer, the library fails to check the length of the source string. This results in an exploitable stack buffer overflow. III. ANALYSIS Exploitation of this vulnerability allows an attacker to execute arbitrary code with the privileges of the "ingres" user. By itself, this vulnerability does not have very serious consequences. However, when combined with the library loading vulnerability, it allows an attacker to execute arbitrary code with root privileges. IV.

BACKGROUND Ingres Database is a database server used in several Computer Associates' products. For example, CA Directory Service use thes Ingres Database server. More information can be found on the vendor's website at the following URL. http://ingres.com/downloads/prod-cert-download.php II. DESCRIPTION Local exploitation of an untrusted library path vulnerability in the "ingvalidpw" utility, as included in Ingres Database 2006 Release 2 for Linux, allows attackers to execute arbitrary code with root privileges. The vulnerability exists within the "ingvalidpw" utility included with Ingres database. This utility is used to verify a user's credentials, and is installed set-uid root. When loading shared libraries, the "ingvalidpw" program will load libraries from a directory owned by the "ingres" user. By using a specially crafted library, a user with "ingres" privileges can gain root. III. ANALYSIS Exploitation of this vulnerability allows an attacker to elevate their privileges from the "ingres" user to root. By itself, this is not that serious of a vulnerability. However, when combined with the libbecompat and verifydb vulnerabilities it allows an unprivileged local user to gain root privileges. IV. DETECTION iDefense has confirmed the existence of this vulnerability in Ingres 2006 Enterprise Edition Release 2 for Linux x86 (32-bit). Other versions may also be affected. V. WORKAROUND iDefense is currently unaware of any workarounds for this issue. VI.
