Integer overflow in sysepollwait in eventpoll.c for Linux kernel 2.6 to 2.6.11 allows local users to overwrite kernel memory via a large number of events.
lppasswd in CUPS 1.1.22 ignores write errors when modifying the CUPS passwd file, which allows local users to corrupt the file by filling the associated file system and triggering the write errors.
lppasswd in CUPS 1.1.22, when run in environments that do not ensure that file descriptors 0, 1, and 2 are open when lppasswd is called, does not verify that the passwd.new file is different from STDERR, which allows local users to control output to passwd.new via certain user input that triggers an error message.
Integer overflow in the vcresize function in the Linux kernel 2.4 and 2.6 before 2.6.10 allows local users to cause a denial of service (kernel crash) via a short new screen value, which leads to a buffer overflow.
Integer overflow in the ipoptionsget function in the Linux kernel before 2.6.10 allows local users to cause a denial of service (kernel crash) via a cmsglen that contains a -1, which leads to a buffer overflow.
Memory leak in the ipoptionsget function in the Linux kernel before 2.6.10 allows local users to cause a denial of service (memory consumption) by repeatedly calling the ipcmsgsend function.
KDE 3.2.x and 3.3.0 through 3.3.2, when saving credentials that are (1) manually entered by the user or (2) created by the SMB protocol handler, stores those credentials for plaintext in the user's .desktop file, which may be created with world-readable permissions, which could allow local users to obtain usernames and passwords for remote resources such as SMB shares.
The openexec function in the execve functionality (exec.c) in Linux kernel 2.4.x up to 2.4.27, and 2.6.x up to 2.6.8, allows local users to read non-readable ELF binaries by using the interpreter (PTINTERP) functionality.
The binfmt functionality in the Linux kernel, when "memory overcommit" is enabled, allows local users to cause a denial of service (kernel oops) via a malformed a.out binary.
The netatalk package in Trustix Secure Linux 1.5 through 2.1, and possibly other operating systems, allows local users to overwrite files via a symlink attack on temporary files.
