RHBA-2011:1486 - gawk bug fix update

Synopsis

gawk bug fix update

Type/Severity

Bug Fix Advisory (none)

Topic

An updated gawk package that fixes a bug is now available for Red Hat Enterprise Linux 5.

Description

The gawk package contains the GNU version of awk, a text processing utility. Awk interprets a special-purpose programming language to do quick and easy text pattern matching and reformatting jobs.

This updated gawk package fixes the following bug:

• Prior to this update gawk interpreted (under certain circumstances) some run-time variables as internal zero-length variable prototypes. When gawk tried to free such run-time variables, it actually freed the internal prototypes, that were allocated just once due to memory savings. Consequently gawk sometimes failed and the error message "awk: double free or corruption" was displayed. With this update the problem has been corrected and the error no longer occurs. (BZ#629196)

All users of gawk are advised to upgrade to this updated package, which fixes this bug.

Solution

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