The kernel in Red Hat Enterprise Linux 3, when running on SMP systems, allows local users to cause a denial of service (deadlock) by running the shmat function on an shm at the same time that shmctl is removing that shm (IPC_RMID), which prevents a spinlock from being unlocked.

kdesktop_lock in kdebase before 3.1.3-5.11 for KDE in Red Hat Enterprise Linux (RHEL) 3 does not properly terminate, which can prevent the screensaver from activating or prevent users from manually locking the desktop.

The original patch for a GNU tar directory traversal vulnerability (CVE-2002-0399) in Red Hat Enterprise Linux 3 and 2.1 uses an "incorrect optimization" that allows user-assisted attackers to overwrite arbitrary files via a crafted tar file, probably involving "/../" sequences with a leading "/".

The CCITTFaxStream::CCITTFaxStream function in Stream.cc for xpdf, gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others allows attackers to corrupt the heap via negative or large integers in a CCITTFaxDecode stream, which lead to integer overflows and integer underflows.

Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others, allows attackers to cause a denial of service (infinite loop) via streams that end prematurely, as demonstrated using the (1) CCITTFaxDecode and (2) DCTDecode streams, aka "Infinite CPU spins."

Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others, allows attackers to cause a denial of service (crash) via a crafted FlateDecode stream that triggers a null dereference.

initscripts in Red Hat Enterprise Linux 4 does not properly handle certain environment variables when /sbin/service is executed, which allows local users with sudo permissions for /sbin/service to gain root privileges via unknown vectors.

init_dev in tty_io.c in the Red Hat backport of NPTL to Red Hat Enterprise Linux 3 does not properly clear controlling tty's in multi-threaded applications, which allows local users to cause a denial of service (crash) and possibly gain tty access via unknown attack vectors that trigger an access of a pointer to a freed structure.

sysreport 1.3.15 and earlier includes contents of the up2date file in a report, which leaks the password for a proxy server in plaintext and allows local users to gain privileges.

The xattr file system code, as backported in Red Hat Enterprise Linux 3 on 64-bit systems, does not properly handle certain offsets, which allows local users to cause a denial of service (system crash) via certain actions on an ext3 file system with extended attributes enabled.

Stack-based buffer overflow in the ieee_putascii function for nasm 0.98 and earlier allows attackers to execute arbitrary code via a crafted asm file, a different vulnerability than CVE-2004-1287.

Race condition in the page fault handler (fault.c) for Linux kernel 2.2.x to 2.2.7, 2.4 to 2.4.29, and 2.6 to 2.6.10, when running on multiprocessor machines, allows local users to execute arbitrary code via concurrent threads that share the same virtual memory space and simultaneously request stack expansion.

The KDE screen saver in KDE before 3.0.5 does not properly check the return value from a certain function call, which allows attackers with physical access to cause a crash and access the desktop session.

Heap-based buffer overflow in less in Red Hat Enterprise Linux 3 allows attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted file, as demonstrated using the UTF-8 locale.

Race condition in gzip 1.2.4, 1.3.3, and earlier, when decompressing a gzipped file, allows local users to modify permissions of arbitrary files via a hard link attack on a file while it is being decompressed, whose permissions are changed by gzip after the decompression is complete.

The patch for integer overflow vulnerabilities in Xpdf 2.0 and 3.0 (CVE-2004-0888) is incomplete for 64-bit architectures on certain Linux distributions such as Red Hat, which could leave Xpdf users exposed to the original vulnerabilities.

Unknown vulnerability in the Linux kernel before 2.4.23, on the AMD AMD64 and Intel EM64T architectures, associated with "setting up TSS limits," allows local users to cause a denial of service (crash) and possibly execute arbitrary code.

Race condition in the (1) load_elf_library and (2) binfmt_aout function calls for uselib in Linux kernel 2.4 through 2.429-rc2 and 2.6 through 2.6.10 allows local users to execute arbitrary code by manipulating the VMA descriptor.

Unknown vulnerability in the system call filtering code in the audit subsystem for Red Hat Enterprise Linux 3 allows local users to cause a denial of service (system crash) via unknown vectors.

The 64 bit ELF support in Linux kernel 2.6 before 2.6.10, on 64-bit architectures, does not properly check for overlapping VMA (virtual memory address) allocations, which allows local users to cause a denial of service (system crash) or execute arbitrary code via a crafted ELF or a.out file.
