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.
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.
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.
iDefense is currently unaware of any workaround for this issue.
"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."
