RHBA-2012:0247 - Bug Fix Advisory

Topic

Updated mod_revocator packages that fix four bugs are now available for Red Hat
Enterprise Linux 5.

Description

The mod_revocator module retrieves and installs remote Certificate Revocation
Lists (CRLs) into an Apache web server.

This update fixes the following bugs:

• Prior to this update, the mod_revoc module could not shut down the httpd

server on 32-bit platforms and the error log infinitely reported the error
message "service httpd status httpd (pid ) when an expired CRL was downloaded.
This update modifies mod_revocator so that the httpd server can correctly shut
down and the error log now reports the error message "service httpd status httpd
dead but subsys locked". (716355)

• Prior to this update, the mod_revoc module could not shut down the httpd

server on 32-bit platforms when CRLUpdate failed. This update modifies
mod_revocator so that the httpd server can correctly shut down when updating the
CRL fails. (716361)

• Prior to this update, httpd failed to start if the 32-bit mod_revocator was

installed on a 64-bit PowerPC platform. This update modifies the initialization
size of the static array. Now, httpd servicestarts as expected. (716874)

• Prior to this update, CRLs could, under certain circumsatances, silently fail

to be downloaded without any error message when the mod_revocator module was
loaded successfully. This update resolves two segmentation violations. In
addition, the setsebool -P httpd_can_network_connect=1 command can now be used
to allow httpd to connect to a remote port which SELinux would otherwise deny
when running mod_revocator. Now, CRLs are downloaded correctly when the
mod_revocator module is running. (737556)

All users of mod_revocator are advised to upgrade to these updated packages,
which fix these bugs.
