RHBA-2014:0998 - Bug Fix Advisory

Topic

Updated log4cpp packages that fix one bug are now available for Red Hat
Enterprise Linux 6.

Description

log4cpp is a library of C++ classes for flexible logging to files, syslog,
IDSA and other destinations. It is modeled after the Log for Java library
(http://www.log4j.org), staying as close to their API as is reasonable.

This update fixes the following bug:

• When logging a formatted string with a variable number of parameters, an

internal buffer is being allocated. For each such allocated buffer, a test
checks if it is large enough to hold the logged string. If a buffer is too
small, a larger one is allocated. However, the tests continued to iterate
through the parameter list even after allocation. As a consequence, when a
string larger than 1024 bytes was being logged, log4cpp terminated with a
segmentation fault. To fix this bug, the tests are now performed on a copy of
the arguments list. As a result, log4cpp no longer crashes when logging a string
larger than 2014 bytes. (BZ#1125130)

Users of log4cpp are advised to upgrade to these updated packages, which fix
this bug.
