A certain ActiveX control in NOS Microsystems getPlus Download Manager (aka DLM or Downloader) 1.5.2.35, as used in Adobe Download Manager, improperly validates requests involving web sites that are not in subdomains, which allows remote attackers to force the download and installation of arbitrary programs via a crafted name for a download site.

The Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.7 before 1.7.2, and 1.8 alpha, allows remote attackers to cause a denial of service (assertion failure and daemon crash) via an invalid (1) AS-REQ or (2) TGS-REQ request.

The Hyper-V server implementation in Microsoft Windows Server 2008 Gold, SP2, and R2 on the x64 platform allows guest OS users to cause a denial of service (host OS hang) via a crafted application that executes a malformed series of machine instructions, aka "Hyper-V Instruction Set Validation Vulnerability."

The SMB implementation in the Server service in Microsoft Windows 2000 SP4, Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista Gold, SP1, and SP2, Windows Server 2008 Gold, SP2, and R2, and Windows 7 does not properly validate the share and servername fields in SMB packets, which allows remote attackers to cause a denial of service (system hang) via a crafted packet, aka "SMB Null Pointer Vulnerability."

The SMB implementation in the Server service in Microsoft Windows 2000 SP4, Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista Gold, SP1, and SP2, Windows Server 2008 Gold, SP2, and R2, and Windows 7 does not properly validate request fields, which allows remote authenticated users to execute arbitrary code via a malformed request, aka "SMB Pathname Overflow Vulnerability."

The SMB client implementation in Microsoft Windows 2000 SP4, XP SP2 and SP3, and Server 2003 SP2 does not properly validate response fields, which allows remote SMB servers and man-in-the-middle attackers to execute arbitrary code via a crafted response, aka "SMB Client Pool Corruption Vulnerability."

PyGIT.py in the Trac Git plugin (trac-git) before 0.0.20080710-3+lenny1 and before 0.0.20090320-1 on Debian GNU/Linux, when enabled in Trac, allows remote attackers to execute arbitrary commands via shell metacharacters in a crafted HTTP query that is used to generate a certain git command.

Geo++ GNCASTER 1.4.0.7 and earlier allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via multiple requests for a non-existent file using a long URI.

client/mount.cifs.c in mount.cifs in smbfs in Samba 3.4.5 and earlier does not verify that the (1) device name and (2) mountpoint strings are composed of valid characters, which allows local users to cause a denial of service (mtab corruption) via a crafted string.

Asterisk Open Source 1.6.0.x before 1.6.0.22, 1.6.1.x before 1.6.1.14, and 1.6.2.x before 1.6.2.2, and Business Edition C.3 before C.3.3.2, allows remote attackers to cause a denial of service (daemon crash) via an SIP T.38 negotiation with an SDP FaxMaxDatagram field that is (1) missing, (2) modified to contain a negative number, or (3) modified to contain a large number.

mystring.c in hybserv in IRCD-Hybrid (aka Hybrid2 IRC Services) 1.9.2 through 1.9.4 allows remote attackers to cause a denial of service (daemon crash) via a ":help \t" private message to the MemoServ service.

FreeBit ServersMan 3.1.5 on Apple iPhone OS 3.1.2, and iPhone OS for iPod touch, allows remote attackers to cause a denial of service (daemon crash) via a HEAD request for the / URI.

ejabberd_c2s.erl in ejabberd before 2.1.3 allows remote attackers to cause a denial of service (daemon crash) via a large number of c2s (aka client2server) messages that trigger a queue overload.

The ucode_ioctl function in intel/io/ucode_drv.c in Sun Solaris 10 and OpenSolaris snv_69 through snv_133, when running on x86 architectures, allows local users to cause a denial of service (panic) via a request with a 0 size value to the UCODE_GET_VERSION IOCTL, which triggers a NULL pointer dereference in the ucode_get_rev function, related to retrieval of the microcode revision.

lib/rfc1035.c in Squid 2.x, 3.0 through 3.0.STABLE22, and 3.1 through 3.1.0.15 allows remote attackers to cause a denial of service (assertion failure) via a crafted DNS packet that only contains a header.

The huft_build function in inflate.c in gzip before 1.3.13 creates a hufts (aka huffman) table that is too small, which allows remote attackers to cause a denial of service (application crash or infinite loop) or possibly execute arbitrary code via a crafted archive. NOTE: this issue is caused by a CVE-2006-4334 regression.
