(This is a re-release of the previous errata caused by a missing patch). A locally-exploitable security hole was found where a normal user could trick root running GnoRPM into writing to arbitrary files due to a bug in the gnorpm tmp file handling. 2000-11-27: Added packages for Red Hat Linux 7 for Alpha

A new modutils-

ghostscript makes use of mktemp instead of mkstemp to create temp files; and also uses improper LD_RUN_PATH values, causing it to search for libraries in the current directory. 2000-11-27: Added packages for Red Hat Linux 7 for Alpha

If you are any setuid applications that use ncurses and its cursor movement functionality, local users may gain access to the program's privileges. 2000-11-27: Added packages for Red Hat Linux 7 for Alpha

Updated bash (1.x) packages for Red Hat Linux 5.x and 6.x, fixing a security problem, are available.

New Netscape packages are available that fix a buffer overflow in parsing HTML. It is recommended that all Netscape users update to the fixed packages. 2000-11-27: Added packages for Red Hat Linux 7 for Alpha

Maurycy Prodeus found a problem in cons.saver, a screensaver for the console that is included in the mc package. cons.saver does not check if it is started with a valid stdout, which combined with a bug in its check to see if its argument is a tty (it forgot to close the file-descriptor after opening the supposed tty) causes it to write a NUL character to the file given as its parameter.

openssh is an implementation of the secure shell protocol, available under the BSD license, primarily maintained by the OpenBSD Project.

ghostscript uses temporary files to do some of its work. Unfortunately the method used to create those files wasn't secure: mktemp was used to create a name for a temporary file, but the file was not opened safely. A second problem is that during build the LD_RUN_PATH environment variable was set to the empty string, which causes the dynamic linker to look in the current directory for shared libraries.

Sebastian Krahmer raised an issue in modutils. In an ideal world modprobe should trust the kernel to only pass valid parameters to modprobe. However he has found at least one local root exploit because high level kernel code passed unverified parameters direct from the user to modprobe. So modprobe no longer trusts kernel input and switches to a safemode.

Guido Bakker has reported a local root vulnerability that can result in local users gaining root permission on a host running koules.sndsrv.linux using a buffer overflow.

Topi Miettinen audited elvis-tiny and raised an issue covering the use and creation of temporary files. Those files are created with a predictable pattern and O_EXCL flag is not used when opening. This makes users of elvis-tiny vulnerable to race conditions and/or data lossage.

The Debian GNU/Linux xmcd package has historically installed two setuid helpers for accessing cddb databases and SCSI cdrom drives. More recently, the package offered the administrator the chance to remove these setuid flags, but did so incorrectly.

The version of the ncurses display library shipped with Debian GNU/Linux 2.2 is vulnerable to several buffer overflows in the parsing of terminfo database files. This problem was discovered by Jouko Pynnönen <jouko@solutions.fi>. The problems are only exploitable in the presence of setuid binaries linked to ncurses which use these particular functions, including xmcd versions before 2.5pl1-7.1.
