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.

All three of these commands use rhosts-style authentication. The rcp protocol allows a server to instruct a client to write to arbitrary files outside of the current directory. This could potentially cause a security issue if a user uses rcp to copy files from a malicious server. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0175 to this issue. These updated packages also address the following bugs: The rexec command failed with "Invalid Argument", because the code used sigaction() as an unsupported signal. The rlogind server reported "SIGCHLD set to SIG_IGN but calls wait()" message to the system log because the original BSD code was ported incorrectly to linux. The rexecd server did not function on systems where client hostnames were not in the DNS service, because server code called gethostbyaddr() for each new connection. The rcp command incorrectly used the "errno" variable and produced erroneous error messages. The rexecd command ignored settings in the /etc/security/limits file, because the PAM session was incorrectly initialized. The rexec command prompted for username and password regardless of the ~/.netrc configuration file contents. This updated package contains a patch that no longer skips the ~/.netrc file.

CVE-2004-0452 CVE-2005-0155 CVE-2005-0156 cpe://redhat:enterprise_linux:3 Red Hat Enterprise Linux 3 OpenSSH is OpenBSD's SSH (Secure SHell) protocol implementation. SSH replaces rlogin and rsh, and provides secure encrypted communications between two untrusted hosts over an insecure network. X11 connections and arbitrary TCP/IP ports can also be forwarded over a secure channel. Public key authentication can be used for "passwordless" access to servers. The scp protocol allows a server to instruct a client to write to arbitrary files outside of the current directory. This could potentially cause a security issue if a user uses scp to copy files from a malicious server. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0175 to this issue. These updated packages also correct the following bugs: On systems where direct ssh access for the root user was disabled by configuration (setting "PermitRootLogin no"), attempts to guess the root password could be judged as sucessful or unsucessful by observing a delay. On systems where the privilege separation feature was turned on, the user resource limits were not correctly set if the configuration specified to raise them above the defaults. It was also not possible to change an expired password. Users of openssh should upgrade to these updated packages, which contain backported patches to resolve these issues.

Evolution includes a mailer, calendar, contact manager, and communication facility. The tools which make up Evolution are tightly integrated with one another and act as a seamless personal information management tool. A bug was found in Evolution's helper program camel-lock-helper.

CVE-2005-0255 cpe://redhat:enterprise_linux:4 Red Hat Enterprise Linux 3 The following security issues were fixed: The Vicam USB driver did not use the copy_from_user function to access userspace, crossing security boundaries. (CAN-2004-0075) The ext3 and jfs code did not properly initialize journal descriptor blocks. A privileged local user could read portions of kernel memory. (CAN-2004-0177) The terminal layer did not properly lock line discipline changes or pending IO. An unprivileged local user could read portions of kernel memory, or cause a denial of service (system crash). (CAN-2004-0814) A race condition was discovered. Local users could use this flaw to read the environment variables of another process that is still spawning via /proc/.../cmdline. (CAN-2004-1058) A flaw in the execve() syscall handling was discovered, allowing a local user to read setuid ELF binaries that should otherwise be protected by standard permissions. (CAN-2004-1073). Red Hat originally reported this as being fixed by RHSA-2004:549, but the associated fix was missing from that update. Keith Owens reported a flaw in the Itanium unw_unwind_to_user() function. A local user could use this flaw to cause a denial of service (system crash) on the Itanium architecture.

(CAN-2005-0384) A flaw in the Red Hat backport of NPTL to Red Hat Enterprise Linux 3 was discovered that left a pointer to a freed tty structure. A local user could potentially use this flaw to cause a denial of service (system crash) or possibly gain read or write access to ttys that should normally be prevented. (CAN-2005-0403) A flaw in fragment queuing was discovered affecting the netfilter subsystem. On systems configured to filter or process network packets (for example those configured to do firewalling), a remote attacker could send a carefully crafted set of fragmented packets to a machine and cause a denial of service (system crash). In order to sucessfully exploit this flaw, the attacker would need to know (or guess) some aspects of the firewall ruleset in place on the target system to be able to craft the right fragmented packets. (CAN-2005-0449) Missing validation of an epoll_wait() system call parameter could allow a local user to cause a denial of service (system crash) on the IBM S/390 and zSeries architectures.

The ongoing effort to resolve these problems has resulted in a marked improvement in the reliability and scalability of Red Hat Enterprise Linux 3. Some key areas affected by these fixes include the kernel's networking, SATA, TTY, and USB subsystems, as well as the architecture-dependent handling under the ia64, ppc64, and x86_64 directories. Scalability improvements were made primarily in the memory management and file system areas. A flaw in offset handling in the xattr file system code backported to Red Hat Enterprise Linux 3 was fixed.
