Double free vulnerability in the utrace support in the Linux kernel, probably 2.6.18, in Red Hat Enterprise Linux (RHEL) 5 and Fedora Core 6 (FC6) allows local users to cause a denial of service (oops), as demonstrated by a crash when running the GNU GDB testsuite, a different vulnerability than CVE-2008-2365.

Untrusted search path vulnerability in a certain Red Hat build script for Standards Based Linux Instrumentation for Manageability (sblim) libraries before 1-13a.el4_6.1 in Red Hat Enterprise Linux (RHEL) 4, and before 1-31.el5_2.1 in RHEL 5, allows local users to gain privileges via a malicious library in a certain subdirectory of /var/tmp, related to an incorrect RPATH setting, as demonstrated by a malicious libc.so library for tog-pegasus.

Stack-based buffer overflow in NConvert 4.92, GFL SDK 2.82, and XnView 1.93.6 on Windows and 1.70 on Linux and FreeBSD allows user-assisted remote attackers to execute arbitrary code via a crafted format keyword in a Sun TAAC file.

The pppol2tp_recvmsg function in drivers/net/pppol2tp.c in the Linux kernel 2.6 before 2.6.26-rc6 allows remote attackers to cause a denial of service (kernel heap memory corruption and system crash) and possibly have unspecified other impact via a crafted PPPOL2TP packet that results in a large value for a certain length variable.

Untrusted search path vulnerability in a certain Red Hat build script for OpenOffice.org (OOo) 1.1.x on Red Hat Enterprise Linux (RHEL) 3 and 4 allows local users to gain privileges via a malicious library in the current working directory, related to incorrect quoting of the ORIGIN symbol for use in the RPATH library path.

The asn1 implementation in (a) the Linux kernel 2.4 before 2.4.36.6 and 2.6 before 2.6.25.5, as used in the cifs and ip_nat_snmp_basic modules; and (b) the gxsnmp package; does not properly validate length values during decoding of ASN.1 BER data, which allows remote attackers to cause a denial of service (crash) or execute arbitrary code via (1) a length greater than the working buffer, which can lead to an unspecified overflow; (2) an oid length of zero, which can lead to an off-by-one error; or (3) an indefinite length for a primitive encoding.

Integer overflow in the dccp_feat_change function in net/dccp/feat.c in the Datagram Congestion Control Protocol (DCCP) subsystem in the Linux kernel 2.6.18, and 2.6.17 through 2.6.20, allows local users to gain privileges via an invalid feature length, which leads to a heap-based buffer overflow.

Untrusted search path vulnerability in vmware-authd in VMware Workstation 5.x before 5.5.7 build 91707 and 6.x before 6.0.4 build 93057, VMware Player 1.x before 1.0.7 build 91707 and 2.x before 2.0.4 build 93057, and VMware Server before 1.0.6 build 91891 on Linux, and VMware ESXi 3.5 and VMware ESX 2.5.4 through 3.5, allows local users to gain privileges via a library path option in a configuration file.

The International Components for Unicode (ICU) library in Apple Mac OS X before 10.5.3, Red Hat Enterprise Linux 5, and other operating systems omits some invalid character sequences during conversion of some character encodings, which might allow remote attackers to conduct cross-site scripting (XSS) attacks.

The (1) sparc_mmap_check function in arch/sparc/kernel/sys_sparc.c and the (2) sparc64_mmap_check function in arch/sparc64/kernel/sys_sparc.c, in the Linux kernel 2.4 before 2.4.36.5 and 2.6 before 2.6.25.3, omit some virtual-address range (aka span) checks when the mmap MAP_FIXED bit is not set, which allows local users to cause a denial of service (panic) via unspecified mmap calls.

Memory leak in a certain Red Hat patch, applied to vsftpd 2.0.5 on Red Hat Enterprise Linux (RHEL) 5 and Fedora 6 through 8, and on Foresight Linux and rPath appliances, allows remote attackers to cause a denial of service (memory consumption) via a large number of CWD commands, as demonstrated by an attack on a daemon with the deny_file configuration option.

The ssh-vulnkey tool on Ubuntu Linux 7.04, 7.10, and 8.04 LTS does not recognize authorized_keys lines that contain options, which makes it easier for remote attackers to exploit CVE-2008-0166 by guessing a key that was not identified by this tool.

Memory leak in the ipip6_rcv function in net/ipv6/sit.c in the Linux kernel 2.4 before 2.4.36.5 and 2.6 before 2.6.25.3 allows remote attackers to cause a denial of service (memory consumption) via network traffic to a Simple Internet Transition (SIT) tunnel interface, related to the pskb_may_pull and kfree_skb functions, and management of an skb reference count.

The utimensat system call (sys_utimensat) in Linux kernel 2.6.22 and other versions before 2.6.25.3 does not check file permissions when certain UTIME_NOW and UTIME_OMIT combinations are used, which allows local users to modify file times of arbitrary files, possibly leading to a denial of service.

The default configuration of Firebird before 2.0.3.12981.0-r6 on Gentoo Linux sets the ISC_PASSWORD environment variable before starting Firebird, which allows remote attackers to bypass SYSDBA authentication and obtain sensitive database information via an empty password.

Linux kernel before 2.4.21 allows local users to cause a denial of service (kernel panic) via asynchronous input or output on a FIFO special file.

The Xen hypervisor block backend driver for Linux kernel 2.6.18, when running on a 64-bit host with a 32-bit paravirtualized guest, allows local privileged users in the guest OS to cause a denial of service (host OS crash) via a request that specifies a large number of blocks.

The IPsec implementation in Linux kernel before 2.6.25 allows remote routers to cause a denial of service (crash) via a fragmented ESP packet in which the first fragment does not contain the entire ESP header and IV.

Linux kernel 2.6.18, and possibly other versions, when running on AMD64 architectures, allows local users to cause a denial of service (crash) via certain ptrace calls.

Linux kernel before 2.6.25.2 does not apply a certain protection mechanism for fcntl functionality, which allows local users to (1) execute code in parallel or (2) exploit a race condition to obtain "re-ordered access to the descriptor table."
