VMware ESX

VMware ESX Server 1.5.2 before Patch 4 allows local users to execute arbitrary programs as root via certain modified VMware ESX Server environment variables.

The icmp_send function in net/ipv4/icmp.c in the Linux kernel before 2.6.25, when configured as a router with a REJECT route, does not properly manage the Protocol Independent Destination Cache (aka DST) in some situations involving transmission of an ICMP Host Unreachable message, which allows remote attackers to cause a denial of service (connectivity outage) by sending a large series of packets to many destination IP addresses within this REJECT route, related to an "rt_cache leak."

Race condition in the sctp_icmp_proto_unreachable function in net/sctp/input.c in Linux kernel 2.6.11-rc2 through 2.6.33 allows remote attackers to cause a denial of service (panic) via an ICMP unreachable message to a socket that is already locked by a user, which causes the socket to be freed and triggers list corruption, related to the sctp_wait_for_connect function.

hostd-vmdb in VMware ESXi 4.0 through 5.0 and ESX 4.0 through 4.1 allows remote attackers to cause a denial of service (hostd-vmdb service outage) by modifying management traffic.

Multiple race conditions in fs/pipe.c in the Linux kernel before 2.6.32-rc6 allow local users to cause a denial of service (NULL pointer dereference and system crash) or gain privileges by attempting to open an anonymous pipe via a /proc/*/fd/ pathname.

The execve function in the Linux kernel, possibly 2.6.30-rc6 and earlier, does not properly clear the current->clear_child_tid pointer, which allows local users to cause a denial of service (memory corruption) or possibly gain privileges via a clone system call with CLONE_CHILD_SETTID or CLONE_CHILD_CLEARTID enabled, which is not properly handled during thread creation and exit.

net/unix/af_unix.c in the Linux kernel 2.6.31.4 and earlier allows local users to cause a denial of service (system hang) by creating an abstract-namespace AF_UNIX listening socket, performing a shutdown operation on this socket, and then performing a series of connect operations to this socket.

The actions implementation in the network queueing functionality in the Linux kernel before 2.6.36-rc2 does not properly initialize certain structure members when performing dump operations, which allows local users to obtain potentially sensitive information from kernel memory via vectors related to (1) the tcf_gact_dump function in net/sched/act_gact.c, (2) the tcf_mirred_dump function in net/sched/act_mirred.c, (3) the tcf_nat_dump function in net/sched/act_nat.c, (4) the tcf_simp_dump function in net/sched/act_simple.c, and (5) the tcf_skbedit_dump function in net/sched/act_skbedit.c.

The xfs_ioc_fsgetxattr function in fs/xfs/linux-2.6/xfs_ioctl.c in the Linux kernel before 2.6.36-rc4 does not initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via an ioctl call.

The extension parser in slp_v2message.c in OpenSLP 1.2.1, and other versions before SVN revision 1647, as used in Service Location Protocol daemon (SLPD) in VMware ESX 4.0 and 4.1 and ESXi 4.0 and 4.1, allows remote attackers to cause a denial of service (infinite loop) via a packet with a "next extension offset" that references this extension or a previous extension. NOTE: some of these details are obtained from third party information.

VMware ESX Server 2.0.x before 2.0.2 and 2.x before 2.5.2 patch 4 stores authentication credentials in base 64 encoded format in the vmware.mui.kid and vmware.mui.sid cookies, which allows attackers to gain privileges by obtaining the cookies using attacks such as cross-site scripting (CVE-2005-3619).

The self-extracting installer in the vSphere Client Installer package in VMware vCenter 4.0 before Update 3 and 4.1 before Update 1, VMware ESXi 4.x before 4.1 Update 1, and VMware ESX 4.x before 4.1 Update 1 does not have a digital signature, which might make it easier for remote attackers to spoof the software distribution via a Trojan horse installer.

nfsd in the Linux kernel before 2.6.28.9 does not drop the CAP_MKNOD capability before handling a user request in a thread, which allows local users to create device nodes, as demonstrated on a filesystem that has been exported with the root_squash option.

The configuration of VMware ESX Server 2.x, 2.0.x, 2.1.x, and 2.5.x allows local users to cause a denial of service (shutdown) via the (1) halt, (2) poweroff, and (3) reboot scripts executed at the service console.

Unspecified vulnerability in VMware ESXi 3.5 before ESXe350-200901401-I-SG and ESX 3.5 before ESX350-200901401-SG allows local administrators to cause a denial of service (host crash) via a snapshot with a malformed VMDK delta disk.

The nfs_permission function in fs/nfs/dir.c in the NFS client implementation in the Linux kernel 2.6.29.3 and earlier, when atomic_open is available, does not check execute (aka EXEC or MAY_EXEC) permission bits, which allows local users to bypass permissions and execute files, as demonstrated by files on an NFSv4 fileserver.
