<For ncurses> --------------------------------------------------------------------- Red Hat, Inc. Security Advisory Synopsis: New ncurses packages fixing buffer overrun available Advisory ID: RHSA-2000:115-01 Issue date: 2000-11-23 Updated on: 2000-11-23 Product: Red Hat Linux Keywords: ncurses buffer overrun exploit setuid Cross references: N/A --------------------------------------------------------------------- 1. Topic: If you are any setuid applications that use ncurses and its cursor movement functionality, local users may gain access to the program's privileges. 2. Relevant releases/architectures: Red Hat Linux 6.2 - i386, alpha, sparc Red Hat Linux 6.2EE - i386, alpha, sparc Red Hat Linux 7.0 - i386 3. Problem description: There used to be an overflowable buffer in the part of the ncurses library handling cursor movement. Attackers can force a privileged application to use their own termcap file containing a special terminal entry which will trigger the ncurses vulnerability, allowing them to execute arbitrary code with the privileges of the exploited binary. 4. Solution: For each RPM for your particular architecture, run: rpm -Fvh [filename] where filename is the name of the RPM. 5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info): 20809 - ncurses allows local privilege escalation 6.

Security Advisory Synopsis: new modutils release addresses more local root compromise possibilities Advisory ID: RHSA-2000:108-04 Issue date: 2000-11-16 Updated on: 2000-11-22 Product: Red Hat Linux Keywords: modutils root exploit security Cross references: N/A --------------------------------------------------------------------- 1. Topic: A new modutils-2.3.21 package has been released to correctly enable safe guard measures introduced in modutils-2.3.20. 2. Relevant releases/architectures: Red Hat Linux 6.2 - i386, alpha, sparc Red Hat Linux 7.0 - i386 Red Hat Linux 7.0J - i386 3. Problem description: The previous packages of modutils released to address a local root compromise contained an error in new safe guards that caused them to not properly be enabled when run as root from the kmod process. These new safe guards check the arguments passed to modules. The new 2.3.21 modutils package fixes this error and correctly checks the arguments when running from kmod, limiting kernel module arguments to those specified in /etc/conf.modules (on Red Hat Linux 6.2) or /etc/modules.conf (on Red Hat Linux 7). This release supersedes the previous modutils errata packages. 4. Solution: For each RPM for your particular architecture, run: rpm -Fvh [filename] where filename is the name of the RPM. 2000-11-17: For Red Hat Linux 6.2, if you installed the previous modutils-2.3.20-0.6.2 packages, you will need to run: mv /etc/modules.conf /etc/conf.modules 5.

Security Advisory Synopsis: ghostscript uses mktemp instead of mkstemp, and uses an improper LD_RUN_PATH Advisory ID: RHSA-2000:114-03 Issue date: 2000-11-22 Updated on: 2000-11-22 Product: Red Hat Linux Keywords: ghostscript mktemp LD_RUN_PATH Cross references: N/A --------------------------------------------------------------------- 1.

Problem description: ghostscript makes use of mktemp to create temp files, which is an insecure and predictable apporoach, it is now patched to use mkstemp, which avoid the race condition on the name. It also uses improper LD_RUN_PATH values, causing ghostscript to search for libraries to load in current directorys. 4.
