Cross-site scripting (XSS) vulnerability in modstatus.c in the modstatus module in Apache HTTP Server (httpd), when ExtendedStatus is enabled and a public server-status page is used, allows remote attackers to inject arbitrary web script or HTML via unspecified vectors involving charsets with browsers that perform "charset detection" when the content-type is not specified.

PerlRun.pm in Apache modperl before 1.30, and RegistryCooker.pm in modperl 2.x, does not properly escape PATHINFO before use in a regular expression, which allows remote attackers to cause a denial of service (resource consumption) via a crafted URI.

Memory leak in the worker MPM (worker.c) for Apache 2, in certain circumstances, allows remote attackers to cause a denial of service (memory consumption) via aborted connections, which prevents the memory for the transaction pool from being reused for other connections.

Off-by-one error in the modssl Certificate Revocation List (CRL) verification callback in Apache, when configured to use a CRL, allows remote attackers to cause a denial of service (child process crash) via a CRL that causes a buffer overflow of one null byte.

Double free vulnerability in the krb5rdcred function for MIT Kerberos 5 (krb5) 1.3.1 and earlier may allow local users to execute arbitrary code.
