Enterprise Linux Security Vulnerabilities - 2006

CVE-2003-0986

Various routines for the ppc64 architecture on Linux kernel 2.6 prior to 2.6.2 and 2.4 prior to 2.4.24 do not use the copy_from_user function when copying data from userspace to kernelspace, which crosses security boundaries and allows local users to cause a denial of service.

CVE-2003-1295

Unspecified vulnerability in xscreensaver 4.12, and possibly other versions, allows attackers to cause xscreensaver to crash via unspecified vectors "while verifying the user-password."

CVE-2005-1918

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 "/".

CVE-2005-3624

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.

CVE-2005-3625

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."

CVE-2005-3626

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.

CVE-2005-3629

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.

CVE-2006-2933

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.

CVE-2006-3813

A regression error in the Perl package for Red Hat Enterprise Linux 4 omits the patch for CVE-2005-0155, which allows local users to overwrite arbitrary files with debugging information.

CVE-2006-4342

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.

CVE-2006-4997

The clip_mkip function in net/atm/clip.c of the ATM subsystem in Linux kernel allows remote attackers to cause a denial of service (panic) via unknown vectors that cause the ATM subsystem to access the memory of socket buffers after they are freed (freed pointer dereference).

CVE-2006-5170

pam_ldap in nss_ldap on Red Hat Enterprise Linux 4, Fedora Core 3 and earlier, and possibly other distributions does not return an error condition when an LDAP directory server responds with a PasswordPolicyResponse control response, which causes the pam_authenticate function to return a success co...

CVE-2006-6235

A "stack overwrite" vulnerability in GnuPG (gpg) 1.x before 1.4.6, 2.x before 2.0.2, and 1.9.0 through 1.9.95 allows attackers to execute arbitrary code via crafted OpenPGP packets that cause GnuPG to dereference a function pointer from deallocated stack memory.
