CVE-2012-2657

Description

From CVE.org

Buffer overflow in the SQLDriverConnect function in unixODBC 2.0.10, 2.3.1, and earlier allows local users to cause a denial of service (crash) via a long string in the FILEDSN option. NOTE: this issue might not be a vulnerability, since the ability to set this option typically implies that the attacker already has legitimate access to cause a DoS or execute code, and therefore the issue would not cross privilege boundaries. There may be limited attack scenarios if isql command-line options are exposed to an attacker, although it seems likely that other, more serious issues would also be exposed, and this issue might not cross privilege boundaries in that context.

Statement

Red Hat does not consider a user assisted client crash such as this to be a security flaw.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

The following CVSS metrics and score provided are preliminary and subject to review.
