rhyt hmbox

the rhythmbox audio player has been updated to version 0.11.6. T his update provides the

option to use proprietary GStreamer plugins.

lftp Rebase

lftp has now been rebased to version 3.7.1. T his applies several upstream feature updates

and bug fixes, including:

A security flaw in the way lft p quoted scripts generated by m irror --script (which

could cause unauthorized privilege escalation) is now fixed.

Using lft p with the option -c no longer causes lftp to hang.

lftp no longer corrupts files during a transfer when using sftp.

For more information on lftp updates applied in this release, refer to http://lftp.yar.ru/news.html.

TTY Input Auditing

TTY input auditing is now supported. If a process is marked for T TY input auditing, the data it

reads from TT Ys is audited; this will show up on audit records with type T T Y.

You can use the pam _tty_audit module to mark a process (and its child processes) for T TY

input auditing. For instructions on how to do this, refer to m an pam _tty_audit(8).

The T T Y audit records contain the exact keystrokes read by the audited process. To make

data decoding easier, bash audits the exact command line using the record type USER_T T Y.

The "T T Y" audit records contain all data read by audited processes from the T T Y. This

includes data inserted into the input stream by the T IOCST I ioctl system call.

SystemTap Re- base

SystemTap has been re-based to version 0.7.2. This update of SystemTap introduces several

minor improvements, along with a few major features. These new features include:

SystemTap now supports symbolic probing on x86, x86-64 and PowerPC architectures.

This enables SystemTap scripts to place probes into user-space applications and shared

libraries. As a result, SystemTap can now provide the same level of debugger probing on

some user-space applications as kernel probing.

For example, if coreutils-debuginfo is installed, you can print a callgraph of the ls

command using

/usr/share/doc/system tap-version/examples/general/callgraph.stp, as in:

stap para-callgraph.stp 'process("ls").function("* ")' -c 'ls -l'

In order to reduce the likelihood of an undetected version mismatch between the binary and

its debuginfo RPMs, Red Hat advises that you set the SYST EMTAP_DEBUGINFO_PATH

environment variable to the value +:.debug:/usr/lib/debug:build.

SystemTap's support for symbolic probes also extends to markers placed into the kernel of

this release. To use these markers, load the kernel-trace kernel module in

/etc/rc.local (using m odprobe kernel-trace).

SystemTap also supports remote compilation services. This enables a single computer on
