SB2014082906 - Gentoo update for Apache HTTP Server

Description

This security bulletin contains information about 3 secuirty vulnerabilities.

1) Input validation error (CVE-ID: CVE-2013-6438)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

The dav_xml_get_cdata function in main/util.c in the mod_dav module in the Apache HTTP Server before 2.4.8 does not properly remove whitespace characters from CDATA sections, which allows remote attackers to cause a denial of service (daemon crash) via a crafted DAV WRITE request.

2) Input validation error (CVE-ID: CVE-2014-0098)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

The log_cookie function in mod_log_config.c in the mod_log_config module in the Apache HTTP Server before 2.4.8 allows remote attackers to cause a denial of service (segmentation fault and daemon crash) via a crafted cookie that is not properly handled during truncation.

3) Heap-based buffer overflow (CVE-ID: CVE-2014-0226)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in Race condition in the mod_status module in the Apache HTTP Server before 2.4.10. A remote attacker can use a crafted request that triggers improper scoreboard handling within the status_handler function in modules to trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
