--------------------------------------------------------------------- Red Hat, Inc. Security Advisory
Synopsis: Potential security problems in ping fixed. Advisory ID: RHSA-2000:087-02 Issue date: 2000-10-17 Updated on: 2000-10-18 Product: Red Hat Linux Keywords: ping buffer overflows Cross references: N/A ---------------------------------------------------------------------
1. Topic:
N/A
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:
Several problems in ping are fixed:
1) Root privileges are dropped after acquiring a raw socket. 2) An 8 byte overflow of a static buffer "outpack" is prevented. 3) An overflow of a static buffer "buf" is prevented.
A non-exploitable root only segfault is fixed as well.
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):
18611 - Unfortunate regression in "ping" security 16677 - "ping -c 1 -s 65690 localhost" segfaults
