The do_mremap function for the mremap system call in Linux 2.2 to 2.2.25, 2.4 to 2.4.24, and 2.6 to 2.6.2, does not properly check the return value from the do_munmap function when the maximum number of VMA descriptors is exceeded, which allows local users to gain root privileges, a different vulnerability than CAN-2003-0985.

An authorization flaw was found in Pacemaker before 1.1.16, where it did not properly guard its IPC interface. An attacker with an unprivileged account on a Pacemaker node could use this flaw to, for example, force the Local Resource Manager daemon to execute a script as root and thereby gain root access on the machine.

Buffer overflow in linuxconf 1.11r11-rh2 on Red Hat Linux 5.1 allows local users to gain root privileges via a long LANG environmental variable.

The Red Hat Linux su program does not log failed password guesses if the su process is killed before it times out, which allows local attackers to conduct brute force password guessing.

xosview 1.5.1 in Red Hat 5.1 allows local users to gain root access via a long HOME environmental variable.

lv reads a .lv file from the current working directory, which allows local users to execute arbitrary commands as other lv users by placing malicious .lv files into other directories.

There is heap-based buffer overflow in Linux kernel, all versions up to, excluding 5.3, in the marvell wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code.

Buffer overflow in newt.c of newt windowing library (libnewt) 0.50.33 and earlier may allow attackers to cause a denial of service or execute arbitrary code in setuid programs that use libnewt.

Kernel logging daemon (klogd) in Linux does not properly cleanse user-injected format strings, which allows local users to gain root privileges by triggering malformed kernel messages.

linuxconf before 1.11.r11-rh3 on Red Hat Linux 5.1 allows local users to overwrite arbitrary files and gain root access via a symlink attack.

Heap corruption vulnerability in the "at" program allows local users to execute arbitrary code via a malformed execution time, which causes at to free the same memory twice.

X.Org server (xorg-server) 1.0.0 and later, X11R6.9.0, and X11R7.0 inadvertently treats the address of the geteuid function as if it is the return value of a call to geteuid, which allows local users to bypass intended restrictions and (1) execute arbitrary code via the -modulepath command line option or (2) overwrite arbitrary files via -logfile.

An out-of-bounds access issue was found in the Linux kernel, all versions through 5.3, in the way Linux kernel's KVM hypervisor implements the Coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be supplied by a host user-space process. An unprivileged host user or process with access to '/dev/kvm' device could use this flaw to crash the host kernel, resulting in a denial of service or potentially escalating privileges on the system.

A vulnerability was found in Linux Kernel, where a Heap Overflow was found in mwifiex_set_wmm_params() function of Marvell Wifi Driver.

There is heap-based buffer overflow in kernel, all versions up to, excluding 5.3, in the marvell wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code.

A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host.

rxvt, when compiled with the PRINT_PIPE option in various Linux operating systems including Linux Slackware 3.0 and RedHat 2.1, allows local users to gain root privileges by specifying a malicious program using the -print-pipe command line parameter.

Buffer overflow in SysVInit in Red Hat Linux 5.1 and earlier allows local users to gain privileges.

ucbmail allows remote attackers to execute commands via shell metacharacters that are passed to it from INN.
