Detail

Several problems have been discovered in Apache2, the next generation, scalable, extendable web server. The Common Vulnerabilities and Exposures project identifies the following problems:

CAN-2005-1268

Marc Stern discovered an off-by-one error in the mod_ssl Certificate Revocation List (CRL) verification callback. When Apache is configured to use a CRL this can be used to cause a denial of service.

CAN-2005-2088

A vulnerability has been discovered in the Apache web server. When it is acting as an HTTP proxy, it allows remote attackers to poison the web cache, bypass web application firewall protection, and conduct cross-site scripting attacks, which causes Apache to incorrectly handle and forward the body of the request.

CAN-2005-2700

A problem has been discovered in mod_ssl, which provides strong cryptography (HTTPS support) for Apache that allows remote attackers to bypass access restrictions.

CAN-2005-2728

The byte-range filter in Apache 2.0 allows remote attackers to cause a denial of service via an HTTP header with a large Range field.

The old stable distribution (woody) does not contain Apache2 packages.

For the stable distribution (sarge) these problems have been fixed in version 2.0.54-5.

For the unstable distribution (sid) these problems have been fixed in version 2.0.54-5.

We recommend that you upgrade your apache2 packages.

Id Description
19188 Apache HTTP Server mod_ssl SSLVerifyClient Per-location Context Restriction B...

mod_ssl contains a flaw that may allow a malicious user to bypass certain security restrictions. The issue is due to an error in enforcing client-based certificate authentication ("SSLVerifyClient require") in per-location context, if "SSLVerifyClient optional" was configured in the global virtual host configuration. It is possible that the flaw may allow an attacker to bypass client-based certificate authentication, resulting in a loss of confidentiality or integrity.
18977 Apache HTTP Server Crafted HTTP Range Header DoS

18286 Apache HTTP Server mod_ssl ssl_callback_SSLVerify_CRL( ) Function Overflow

Apache HTTP Server contains a flaw that may allow a remote attacker to gain privileges. The issue is due to the mod_ssl extension module not properly validating Certificate Revocation Lists (CRL). By sending a crafted CRL, an attacker can exploit an off-by-one error in mod_ssl to cause a buffer overflow. This may allow the attacker to crash the web server or potentially execute arbitrary code.
