Overview

CVE-2006-1902 is a low-severity vulnerability affecting gnu gcc. It was published on April 20, 2006 and has a CVSS 2.0 base score of 2.1 (LOW).

This vulnerability has a CVSS 2.0 base score of 2.1, rated LOW. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

fold_binary in fold-const.c in GNU Compiler Collection (gcc) 4.1 improperly handles pointer overflow when folding a certain expr comparison to a corresponding offset comparison in cases other than EQ_EXPR and NE_EXPR, which might introduce buffer overflow vulnerabilities into applications that could be exploited by context-dependent attackers.NOTE: the vendor states that the essence of the issue is "not correctly interpreting an offset to a pointer as a signed value."

Remediation

Check the references section for vendor advisories and patches from gnu. Update gcc to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
