The nlmclntmarkreclaim in clntlock.c in NFS lockd in Linux kernel before 2.6.16 allows remote attackers to cause a denial of service (process crash) and deny access to NFS exports via unspecified vectors that trigger a kernel oops (null dereference) and a deadlock.

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.

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.
