Source: MITRE
Base Score: 5.0 MEDIUM Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P) (V2 legend) Impact Subscore: 2.9 Exploitability Subscore: 10.0
Access Vector (AV): Network Access Complexity (AC): Low Authentication (AU): None Confidentiality (C): None Integrity (I): None Availability (A): Partial Additional Information: Allows disruption of service
Per: http://httpd.apache.org/security/vulnerabilities_22.html 'A flaw was found in the handling of requests by mod_cache and mod_dav. A malicious remote attacker could send a carefully crafted request and cause a httpd child process to crash. This crash would only be a denial of service if using the worker MPM. This issue is further mitigated as mod_dav is only affected by requests that are most likely to be authenticated, and mod_cache is only affected if the uncommon "CacheIgnoreURLSessionIdentifiers" directive, introduced in version 2.2.14, is used.'
