CVE-2009-0688
Description
From CVE.org
Multiple buffer overflows in the CMU Cyrus SASL library before 2.1.23 might allow remote attackers to execute arbitrary code or cause a denial of service (application crash) via strings that are used as input to the sasl_encode64 function in lib/saslutil.c.
Statement
The upstream fix for this issue is not backwards compatible and introduces an ABI change not allowed in Red Hat Enterprise Linux. Therefore, there is no plan to address this problem directly in cyrus-sasl packages.
All applications shipped in Red Hat Enterprise Linux and using affected sasl_encode64() function were investigated and patched if their use of the function could have security consequences. See following bug report for further details: https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2009-0688#c20
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).
