The ap_log_rerror function in Apache 2.0 through 2.035, when a CGI application encounters an error, sends error messages to the client that include the full path for the server, which allows remote attackers to obtain sensitive information.

httpd: allows local users to overwrite arbitrary files via a symlink attack

htpasswd and htdigest in Apache 2.0a9, 1.3.14, and others allows local users to overwrite arbitrary files via a symlink attack.

The check_forensic script in apache-utils package 1.3.31 allows local users to overwrite or create arbitrary files via a symlink attack on temporary files.

mod_digest_apple for Apache 1.3.31 and 1.3.32 on Mac OS X Server does not properly verify the nonce of a client response, which allows remote attackers to replay credentials.

A regression error in the Debian distributions of the apache-ssl package (before 1.3.9 on Debian 2.2, and before 1.3.26 on Debian 3.0), for Apache 1.3.27 and earlier, allows local users to read or modify the Apache password file via a symlink attack on temporary files when the administrator runs (1) htpasswd or (2) htdigest, a re-introduction of a vulnerability that was originally identified and addressed by CVE-2001-0131.

security flaw

Apache webserver 2.0.52 and earlier allows remote attackers to cause a denial of service (CPU consumption) via an HTTP GET request with a MIME header containing multiple lines with a large number of space characters.

httpd mod_include SSI overflow

Buffer overflow in the get_tag function in mod_include for Apache 1.3.x to 1.3.32 allows local users who can create SSI documents to execute arbitrary code as the apache user via SSI (XSSI) documents that trigger a length calculation error.

Apache 2.0.42 allows remote attackers to view the source code of a CGI script via a POST request to a directory with both WebDAV and CGI enabled.

PHP 3.x (PHP3) on Apache 1.3.6 allows remote attackers to read arbitrary files via a modified .. (dot dot) attack containing "%5c" (encoded backslash) sequences.

Apache WWW server 1.3.1 and earlier allows remote attackers to cause a denial of service (resource exhaustion) via a large number of MIME headers with the same name, aka the "sioux" vulnerability.

mod_ssl SSLCipherSuite bypass

The mod_ssl module in Apache 2.0.35 through 2.0.52, when using the "SSLCipherSuite" directive in directory or location context, allows remote clients to bypass intended restrictions by using any cipher suite that is allowed by the virtual host configuration.

Unknown vulnerability in Apache 2.0.51 prevents "the merging of the Satisfy directive," which could allow attackers to obtain access to restricted resources contrary to the specified authentication configuration.

security flaw

Buffer overflows in the ApacheBench benchmark support program (ab.c) in Apache before 1.3.27, and Apache 2.x before 2.0.43, allow a malicious web server to cause a denial of service and possibly execute arbitrary code via a long response.

security flaw

The mod_dav module in Apache 2.0.50 and earlier allows remote attackers to cause a denial of service (child process crash) via a certain sequence of LOCK requests for a location that allows WebDAV authoring access.

security flaw

The IPv6 URI parsing routines in the apr-util library for Apache 2.0.50 and earlier allow remote attackers to cause a denial of service (child process crash) via a certain URI, as demonstrated using the Codenomicon HTTP Test Tool.

security flaw

Cross-site scripting (XSS) vulnerability in the default error page of Apache 2.0 before 2.0.43, and 1.3.x up to 1.3.26, when UseCanonicalName is "Off" and support for wildcard DNS is present, allows remote attackers to execute script as other web page visitors via the Host: header, a different vulnerability than CAN-2002-1157.

Vulnerability in Apache httpd before 1.3.11, when configured for mass virtual hosting using mod_rewrite, or mod_vhost_alias in Apache 1.3.9, allows remote attackers to retrieve arbitrary files.

security flaw

The char_buffer_read function in the mod_ssl module for Apache 2.x, when using reverse proxying to an SSL server, allows remote attackers to cause a denial of service (segmentation fault).

security flaw

mod_ssl in Apache 2.0.50 and earlier allows remote attackers to cause a denial of service (CPU consumption) by aborting an SSL connection in a way that causes an Apache child process to enter an infinite loop.

security flaw

The shared memory scoreboard in the HTTP daemon for Apache 1.3.x before 1.3.27 allows any user running as the Apache UID to send a SIGUSR1 signal to any process as root, resulting in a denial of service (process kill) or possibly other behaviors that would not normally be allowed, by modifying the parent[].pid and parent[].last_rtime segments in the scoreboard.
