| Description: | From the Mandriva advisory: The log_cookie function in mod_log_config.c in the mod_log_config module in the Apache HTTP Server 2.2.17 through 2.2.21, when a threaded MPM is used, does not properly handle a \%{}C format string, which allows remote attackers to cause a denial of service (daemon crash) via a cookie that lacks both a name and a value (CVE-2012-0021). scoreboard.c in the Apache HTTP Server 2.2.21 and earlier might allow local users to cause a denial of service (daemon crash during shutdown) or possibly have unspecified other impact by modifying a certain type field within a scoreboard shared memory segment, leading to an invalid call to the free function (CVE-2012-0031). protocol.c in the Apache HTTP Server 2.2.x through 2.2.21 does not properly restrict header information during construction of Bad Request (aka 400) error documents, which allows remote attackers to obtain the values of HTTPOnly cookies via vectors involving a (1) long or (2) malformed header in conjunction with crafted web script (CVE-2012-0053). | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
