Red Hat OVAL Patch Definition Merger 2 5.3 2008-01-23T07:23:41 Red Hat Enterprise Linux 3 Cdrecord is an application for recording audio and data CDs. Cdrecord works with many different brands of CD recorders, fully supports multi-sessions, and provides human-readable error messages. The cdrecord package on Red Hat Enterprise Linux does not require setuid root for use by normal users. The permissions of the writer device are changed by pam_console_apply at console login. Setting the uid of cdrecord to root opens a vulnerability to possible exploitation. All users of cdrecord that setuid root should upgrade to these updated packages, which resolve this issue.

CVE-2004-0806 cpe://redhat:enterprise_linux:3 Red Hat Enterprise Linux 3 GDB, the GNU debugger, allows debugging of programs written in C, C++, and other languages, by executing them in a controlled fashion, and then printing their data. This updated package addresses the following issues: - GDB on ia64 had previously implemented a bug fix to work-around a kernel problem when creating a core file via gcore. The bug fix caused a significant slow-down of gcore. - GDB on Itanium issued an extraneous warning when gcore was used. - GDB on Itanium could not successfully do an info frame for a signal trampoline. - GDB on AMD64 and Intel EM64T had problems attaching to a 32-bit process. - GDB on AMD64 and Intel EM64T was not properly handling threaded watchpoints. - GDB could not build with gcc4 when -Werror flag was set. - GDB had problems printing inherited members of C++ classes. - A few updates from mainline sources concerning Dwarf2 partial die in cache support, follow-fork support, interrupted syscall support, and DW_OP_piece read support. All users of gdb should upgrade to these updated packages, which resolve these issues. Copyright 2005 Red Hat, Inc.

The lppasswd utility ignores write errors when modifying the CUPS passwd file. A local user who is able to fill the associated file system could corrupt the CUPS password file or prevent future uses of lppasswd.

An attacker who has the ability to send a malicious HPGL file to a printer could possibly execute arbitrary code as the "lp" user. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-1267 to this issue. A buffer overflow flaw was found in the Decrypt::makeFileKey2 function of Xpdf which also affects the CUPS pdftops filter due to a shared codebase. An attacker who has the ability to send a malicious PDF file to a printer could possibly execute arbitrary code as the "lp" user. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0064 to this issue. The lppasswd utility was found to ignore write errors when modifying the CUPS passwd file. A local user who is able to fill the associated file system could corrupt the CUPS password file or prevent future uses of lppasswd. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CAN-2004-1268 and CAN-2004-1269 to these issues. The lppasswd utility was found to not verify that the passwd.new file is different from STDERR, which could allow local users to control output to passwd.new via certain user input that triggers an error message. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-1270 to this issue. All users of cups should upgrade to these updated packages, which contain backported patches to resolve these issues. Important Copyright 2005 Red Hat, Inc.
