RHBA-2013:1337 - zsh bug fix update

Synopsis

zsh bug fix update

Type/Severity

Bug Fix Advisory (none)

Topic

Updated zsh packages that fix one bug are now available for Red Hat Enterprise Linux 5.

Description

The zsh shell is a command interpreter which can be used as an interactive login shell and as a shell script command processor. Zsh resembles the ksh shell (the Korn shell), but includes many enhancements. Zsh supports command line editing, built-in spelling correction, programmable command completion, shell functions (with autoloading), a history mechanism, and more.

This update fixes the following bug:

  • Due to a missing error flag check, validating the syntax of a comparison expression (one that compares values with the less-than or greater-than signs) as the condition of a while loop did not exit and return a single error message as expected, but entered an infinite loop instead, returning a "bad math expression" error message at every iteration of the loop. With this update, in case an evaluated loop condition is not valid, the script that uses it exits after the first iteration of the loop with an error message and exit code 2. (BZ#813219)

Users of zsh are advised to upgrade to these updated packages, which fix this bug.

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.
