RHBA-2013:0118 - Bug Fix Advisory

Topic

Updated psmisc packages that fix multiple bugs are now available for Red Hat
Enterprise Linux 5.

Description

The psmisc package contains the pstree, killall, and fuser utilities to manage
system processes.

This update fixes the following bugs:

• Prior to this update, the fuser utility incorrectly used the "/proc/net/tcp"

socket table to list processes. As a consequence, the fuser tool did not list
processes that use a UDP port as expected. This update modifies the underlying
code to parse the correct "/proc/net/udp" socket table, and fuser now lists
processes for UDP ports as expected. (BZ#479345)

• Prior to this update, memory was not correctly allocated. As a consequence,

the "killall -g" option could fail to kill a process group. This update modifies
the memory allocation. Now, the killall utility works as expected. (BZ#666213)

• Prior to this update, IPv6 addresses were not correctly handled. As a

consequence, the fuser command could return empty output for IPv6 sockets. This
update modifies the code to handle IPv6 addresses as expected. Now, IPv6 sockets
are identified correctly. (BZ#693476)

All users of psmisc are advised to upgrade to these updated packages, which fix
these bugs.
