Summary
Red Hat Security Advisory: : Updated mc packages resolve buffer overflow vulnerability
Severity
Important
Notes
Topic: Updated mc packages that resolve a buffer overflow vulnerability are now available.
Details: Midnight Commander is a visual shell much like a file manager. A buffer overflow has been found in Midnight Commander's virtual filesystem code. Specifically, a stack-based buffer overflow in vfs_s_resolve_symlink of vfs/direntry.c allows remote attackers to execute arbitrary code during symlink conversion. Users of Midnight Commander should install these updated packages, which resolve this issue.

CVE-2003-1023

Stack-based buffer overflow in vfs_s_resolve_symlink of vfs/direntry.c for Midnight Commander (mc) 4.6.0 and earlier, and possibly later versions, allows remote attackers to execute arbitrary code during symlink conversion.

Vendor Fix Before applying this update, make sure all previously released errata relevant to your system have been applied. To update all RPMs for your particular architecture, run: rpm -Fvh [filenames] where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs. Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. If up2date fails to connect to Red Hat Network due to SSL Certificate Errors, you need to install a version of the up2date client with an updated certificate. The latest version of up2date is available from the Red Hat FTP site and may also be downloaded directly from the RHN website: https://rhn.redhat.com/help/latest-up2date.pxt https://access.redhat.com/errata/RHSA-2004:034
