Vulnerability from csaf_redhat - Published: 2001-05-17 01:32 - Updated: 2024-11-21 22:05
Summary
Red Hat Security Advisory: : Updated Kerberos 5 packages available

Notes

Topic
Updated Kerberos 5 packages are now available for Red Hat Linux 6.2, 7, and 7.1. These updates close a potential vulnerability present in the gssapi-aware ftpd included in the krb5-workstation package.
Details
By use of a carefully-crafted authentication request, a malicious client could exploit a vulnerability made possible by a missing bounds check. A malicious client could also overflow the buffer space used by the server for performing globbing operations.

Only those\nRPMs which are currently installed will be updated.  Those RPMs which are\nnot installed but included in the list will not be updated.  Note that you\ncan also use wildcards (*.rpm) if your current directory *only* contains the\ndesired RPMs.\n\nPlease note that this update is also available via Red Hat Network.  Many\npeople find this an easier way to apply updates.  To use Red Hat Network,\nlaunch the Red Hat Update Agent with the following command:\n\nup2date\n\nThis will start an interactive process that will result in the appropriate\nRPMs being upgraded on your system.",
