The GDM daemon in GNOME Display Manager (GDM) before 2.14.13, 2.16.x before 2.16.7, 2.18.x before 2.18.4, and 2.19.x before 2.19.5 does not properly handle NULL return values from the g_strsplit function, which allows local users to cause a denial of service (persistent daemon crash) via a crafted command to the daemon's socket, related to (1) gdm.c and (2) gdmconfig.c in daemon/, and (3) gdmconfig.c and (4) gdmflexiserver.c in gui/.

The Distributed Lock Manager (DLM) in the cluster manager for Linux kernel 2.6.15 allows remote attackers to cause a denial of service (loss of lock services) by connecting to the DLM port, which probably prevents other processes from accessing the service.

Unspecified vulnerability in the kernel in Red Hat Enterprise Linux (RHEL) 4 on the x86_64 platform allows local users to cause a denial of service (OOPS) via unspecified vectors related to the get_gate_vma function and the fuser command.

Header.pm in Net::DNS before 0.60, a Perl module, (1) generates predictable sequence IDs with a fixed increment and (2) can use the same starting ID for all child processes of a forking server, which allows remote attackers to spoof DNS responses, as originally reported for qpsmtp and spamassassin.

Stack-based buffer overflow in Lhaca File Archiver before 1.21 allows user-assisted remote attackers to execute arbitrary code via a crafted LZH archive, as exploited by malware such as Trojan.Lhdropper.

Buffer overflow in cluster/cman/daemon/daemon.c in cman (redhat-cluster-suite) before 20070622 allows local users to cause a denial of service (crash) and possibly execute arbitrary code via long client messages.

The Avahi daemon in Avahi before 0.6.20 allows attackers to cause a denial of service (exit) via empty TXT data over D-Bus, which triggers an assert error.

Apache httpd 1.3.37, 2.0.59, and 2.2.4 with the Prefork MPM module, allows local users to cause a denial of service by modifying the worker_score and process_score arrays to reference an arbitrary process ID, which is sent a SIGUSR1 signal from the master process, aka "SIGUSR1 killer."

Multiple buffer overflows in libtidy, as used in the Tidy extension for PHP 5.2.3 and possibly other products, allow context-dependent attackers to execute arbitrary code via (1) a long second argument to the tidy_parse_string function or (2) an unspecified vector to the tidy_repair_string function. NOTE: this might only be an issue in environments where vsnprintf is implemented as a wrapper for vsprintf.

PostgreSQL 8.1 and probably later versions, when local trust authentication is enabled and the Database Link library (dblink) is installed, allows remote attackers to access arbitrary accounts and execute arbitrary SQL queries via a dblink host parameter that proxies the connection from 127.0.0.1.

Camel (camel-imap-folder.c) in the mailer component for Evolution Data Server 1.11 allows remote IMAP servers to execute arbitrary code via a negative SEQUENCE value in GData, which is used as an array index.

sudo, when linked with MIT Kerberos 5 (krb5), does not properly check whether a user can currently authenticate to Kerberos, which allows local users to gain privileges, in a manner unintended by the sudo security model, via certain KRB5_ environment variable settings. NOTE: another researcher disputes this vulnerability, stating that the attacker must be "a user, who can already log into your system, and can already use sudo."

Visual truncation vulnerability in Konqueror 3.5.5 allows remote attackers to spoof the address bar and possibly conduct phishing attacks via a long hostname, which is truncated after a certain number of characters, as demonstrated by a phishing attack using HTTP Basic Authentication.

Gimp before 2.8.22 allows context-dependent attackers to cause a denial of service (crash) via an ICO file with an InfoHeader containing a Height of zero, a similar issue to CVE-2007-2237.

The BN_from_montgomery function in crypto/bn/bn_mont.c in OpenSSL 0.9.8e and earlier does not properly perform Montgomery multiplication, which might allow local users to conduct a side-channel attack and retrieve RSA private keys.

The signal handling in the Linux kernel before 2.6.22, including 2.6.2, when running on PowerPC systems using HTX, allows local users to cause a denial of service via unspecified vectors involving floating point corruption and concurrency, related to clearing of MSR bits.

lib/info.c in libvorbis 1.1.2, and possibly other versions before 1.2.0, allows context-dependent attackers to cause a denial of service and possibly execute arbitrary code via invalid (1) blocksize_0 and (2) blocksize_1 values, which trigger a "heap overwrite" in the _01inverse function in res0.c. NOTE: this issue has been RECAST so that CVE-2007-4029 handles additional vectors.

Stack-based buffer overflow in the random number generator (RNG) implementation in the Linux kernel before 2.6.22 might allow local root users to cause a denial of service or gain privileges by setting the default wakeup threshold to a value greater than the output pool size, which triggers writing random numbers to the stack by the pool transfer function involving "bound check ordering". NOTE: this issue might only cross privilege boundaries in environments that have granular assignment of privileges for root.

The sysfs_readdir function in the Linux kernel 2.6, as used in Red Hat Enterprise Linux (RHEL) 4.5 and other distributions, allows users to cause a denial of service (kernel OOPS) by dereferencing a null pointer to an inode in a dentry.

The init.d script for the X.Org X11 xfs font server on various Linux distributions might allow local users to change the permissions of arbitrary files via a symlink attack on the /tmp/.font-unix temporary file.
