-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 +------------------------------------------------------------------------+ | EnGarde Secure Linux Security Advisory March 7, 2003 | | http://www.engardelinux.org/ ESA-20030307-008 | | | | Package: file | | Summary: ELF parsing routine buffer overflow vulnerability. | +------------------------------------------------------------------------+ EnGarde Secure Linux is a secure distribution of Linux that features improved access control, host and network intrusion detection, Web based secure remote management, e-commerce, and integrated open source security tools. OVERVIEW - -------- There is a buffer overflow vulnerability in the 'file' command's ELF parsing routines which can allow an attacker to exploit a victim by tricking them into running 'file' on a specially crafted binary. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0102 to this issue. SOLUTION - -------- Users of the EnGarde Professional edition can use the Guardian Digital Secure Network to update their systems automatically. EnGarde Community users should upgrade to the most recent version as outlined in this advisory. Updates may be obtained from: ftp://ftp.engardelinux.org/pub/engarde/stable/updates/ http://ftp.engardelinux.org/pub/engarde/stable/updates/ Before upgrading the package, the machine must either: a) be booted into a "standard" kernel; or b) have LIDS disabled. To disable LIDS, execute the command: # /sbin/lidsadm -S -- -LIDS_GLOBAL To install the updated package, execute the command: # rpm -Uvh files You must now update the LIDS configuration by executing the command: # /usr/sbin/config_lids.pl To re-enable LIDS (if it was disabled), execute the command: # /sbin/lidsadm -S -- +LIDS_GLOBAL To verify the signatures of the updated packages, execute the command: # rpm -Kv files UPDATED PACKAGES - ---------------- These updated packages are for EnGarde Secure Linux Community Edition.
