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.

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).

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.

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.

cPanel, when compiling Apache 1.3.29 and PHP with the mod_phpsuexec option, does not set the --enable-discard-path option, which causes php to use the SCRIPT_FILENAME variable to find and execute a script instead of the PATH_TRANSLATED variable, which allows local users to execute arbitrary PHP code as other users via a URL that references the attacker's script after the user's script, which executes the attacker's script with the user's privileges, a different vulnerability than CVE-2004-0529.

Heap-based buffer overflow in proxy_util.c for mod_proxy in Apache 1.3.25 to 1.3.31 allows remote attackers to cause a denial of service (process crash) and possibly execute arbitrary code via a negative Content-Length HTTP header field, which causes a large amount of data to be copied.

The ap_get_mime_headers_core function in Apache httpd 2.0.49 allows remote attackers to cause a denial of service (memory exhaustion), and possibly an integer signedness error leading to a heap-based buffer overflow on 64 bit systems, via long header lines with large numbers of space or tab characters.

The modified suexec program in cPanel, when configured for mod_php and compiled for Apache 1.3.31 and earlier without mod_phpsuexec, allows local users to execute untrusted shared scripts and gain privileges, as demonstrated using untainted scripts such as (1) proftpdvhosts or (2) addalink.cgi, a different vulnerability than CVE-2004-0490.

Format string vulnerability in the mod_proxy hook functions function in ssl_engine_log.c in mod_ssl before 2.8.19 for Apache before 1.3.31 may allow remote attackers to execute arbitrary messages via format string specifiers in certain log messages for HTTPS that are handled by the ssl_log function.

Stack-based buffer overflow in the ssl_util_uuencode_binary function in ssl_util.c for Apache mod_ssl, when mod_ssl is configured to trust the issuing CA, may allow remote attackers to execute arbitrary code via a client certificate with a long subject DN.

Apache 1.4.x before 1.3.30, and 2.0.x before 2.0.49, when using multiple listening sockets on certain platforms, allows remote attackers to cause a denial of service (blocked new connections) via a "short-lived connection on a rarely-accessed listening socket."

Directory traversal vulnerability in Apache 1.3.29 and earlier, and Apache 2.0.48 and earlier, when running on Cygwin, allows remote attackers to read arbitrary files via a URL containing "..%5C" (dot dot encoded backslash) sequences.

mod_access in Apache 1.3 before 1.3.30, when running big-endian 64-bit platforms, does not properly parse Allow/Deny rules using IP addresses without a netmask, which could allow remote attackers to bypass intended access restrictions.

Memory leak in ssl_engine_io.c for mod_ssl in Apache 2 before 2.0.49 allows remote attackers to cause a denial of service (memory consumption) via plain HTTP requests to the SSL port of an SSL-enabled server.

mod_disk_cache in Apache 2.0 through 2.0.49 stores client headers, including authentication information, on the hard disk, which could allow local users to gain sensitive information.

mod_digest for Apache before 1.3.31 does not properly verify the nonce of a client response by using a AuthNonce secret.

Apache-SSL 1.3.28+1.52 and earlier, with SSLVerifyClient set to 1 or 3 and SSLFakeBasicAuth enabled, allows remote attackers to forge a client certificate by using basic authentication with the "one-line DN" of the target user.

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.

PHP treats unknown methods such as "PoSt" as a GET request, which could allow attackers to intended access restrictions if PHP is running on a server that passes on all methods, such as Apache httpd 2.0, as demonstrated using a Limit directive. NOTE: this issue has been disputed by the Apache security team, saying "It is by design that PHP allows scripts to process any request method. A script which does not explicitly verify the request method will hence be processed as normal for arbitrary methods. It is therefore expected behaviour that one cannot implement per-method access control using the Apache configuration alone, which is the assumption made in this report.

Heap-based buffer overflow in the sec_filter_out function in mod_security 1.7RC1 through 1.7.1 in Apache 2 allows remote attackers to execute arbitrary code via a server side script that sends a large amount of data.
