Microsoft Windows Media Player (WMP) allows remote attackers to cause a denial of service (application crash) via a certain AIFF file that triggers a divide-by-zero error, as demonstrated by kr.aiff.

The iwl_set_rate function in compatible/iwl3945-base.c in iwlwifi 1.1.21 and earlier dereferences an iwl_get_hw_mode return value without checking for NULL, which might allow remote attackers to cause a denial of service (kernel panic) via unspecified vectors during module initialization.

The GetMagicNumberString function in Massive Entertainment World in Conflict 1.000 and earlier allows remote attackers to cause a denial of service (NULL dereference and daemon crash) via a string to the VoIP port (52999/tcp) with an invalid value in the third byte.

Off-by-one error in the do_login_loop function in libwzd-core/wzd_login.c in wzdftpd 0.8.0, 0.8.2, and possibly other versions allows remote attackers to cause a denial of service (daemon crash) via a long USER command that triggers a stack-based buffer overflow. NOTE: some of these details are obtained from third party information.

Multiple integer overflows in Dibbler 0.6.0 allow remote attackers to cause a denial of service (daemon crash) via packets containing options with large lengths, which trigger attempts at excessive memory allocation, as demonstrated by (1) the TSrvMsg constructor in SrvMessages/SrvMsg.cpp; the (2) TClntMsg, (3) TClntOptIAAddress, (4) TClntOptIAPrefix, (5) TOptVendorSpecInfo, and (6) TOptOptionRequest constructors; and the (7) TRelIfaceMgr::decodeRelayRepl, (8) TRelMsg::decodeOpts, and (9) TSrvIfaceMgr::decodeRelayForw methods.

Dibbler 0.6.0 does not verify that certain length parameters are appropriate for buffer sizes, which allows remote attackers to trigger a buffer over-read and cause a denial of service (daemon crash), as demonstrated by incorrect behavior of the TSrvMsg constructor in SrvMessages/SrvMsg.cpp when (1) reading the option code and option length and (2) parsing options.

An exploitable denial-of-service vulnerability exists in the IPv4 functionality of Allen-Bradley MicroLogix 1100 Programmable Logic Controller Systems Series B FRN 16.000, Series B FRN 15.002, Series B FRN 15.000, Series B FRN 14.000, Series B FRN 13.000, Series B FRN 12.000, Series B FRN 11.000 and Series B FRN 10.000. A specially crafted packet can cause a major error, resulting in a denial of service. An attacker can send a malicious packet to trigger this vulnerability.
