The apr_strmatch_precompile function in strmatch/apr_strmatch.c in Apache APR-util before 1.3.5 allows remote attackers to cause a denial of service (daemon crash) via crafted input involving (1) a .htaccess file used with the Apache HTTP Server, (2) the SVNMasterURI directive in the mod_dav_svn module in the Apache HTTP Server, (3) the mod_apreq2 module for the Apache HTTP Server, or (4) an application that uses the libapreq2 library, which triggers a heap-based buffer underflow.

Security readout for executives and security teams

CVE-2009-0023 is an old Apache APR-util flaw that can let a remote attacker crash a daemon through crafted input in specific Apache-related paths. The main business risk is service outage, not confirmed data theft or code execution in the provided sources. Exposure is most likely in legacy systems running APR-util before 1.3.5, especially Apache HTTP Server deployments using the named modules or applications linked to libapreq2. Modern supported distributions are less likely exposed if they include vendor backports. Treat as a legacy availability risk. Prioritize remediation where outdated Apache infrastructure is internet-facing or business-critical, but do not escalate as actively exploited based on this bundle alone. Mitigation focus: Upgrade APR-util to 1.3.5 or a vendor-patched package.; Apply relevant Debian, Fedora, Mandriva, IBM, or other vendor updates.; Review Apache modules and libapreq2 use against vendor guidance..
