5.253. psacct
Updated psacct packages that fix multiple bugs are now available for Red Hat Enterprise Linux 6.
The psacct packages contain utilities for monitoring process activities, including ac, lastcomm, accton, dump-acct, dump-utmp and sa. The "ac" command displays statistics about how long users have been logged on. The "lastcomm" command displays information about previously executed commands. The "accton" command turns process accounting on or off. The "dump-acct" command transforms the output file from the accton format to a human-readable format. The "dump-utmp" command prints utmp files in human-readable format. The "sa" command summarizes information about previously executed commands.
Bug Fixes
- BZ#828728
- Previously, improper data type detection could have caused an arithmetic overflow. As a consequence, the dump-acct tool reported incorrect elapsed time values. A patch has been applied so that correct values are reported with this update.
- BZ#834217
- Previously, improper data type conversion caused the dump-utmp tool to report invalid timestamps. Consequently, mainly on the 64-bit PowerPC architecture, dump-utmp could have terminated unexpectedly with a segmentation fault. A patch has been applied so that correct values are reported and no crashes occur with this update.
- BZ#838998
- Previously, accessing an incorrect and uninitialized memory structure used for acquiring the user IDs caused the sa tool to report incorrect usernames. Consequently, the sa tool could have terminated unexpectedly with a segmentation fault. A patch has been applied so that correct values are reported and no crashes occur with this update.
All users of psacct are advised to upgrade to these updated packages, which fix these bugs.
