Summary:

SELinux is preventing /opt/Yammer/bin/Yammer from loading /opt/Adobe
AIR/Versions/1.0/Resources/libcurl.so which requires text relocation.

Detailed Description:

The Yammer application attempted to load /opt/Adobe
AIR/Versions/1.0/Resources/libcurl.so which requires text relocation. This is a
potential security problem. Most libraries do not need this permission.
Libraries are sometimes coded incorrectly and request this permission. The
SELinux Memory Protection Tests
(http://www.akkadia.org/drepper/selinux-mem.html) web page explains how to
remove this requirement. You can configure SELinux temporarily to allow
/opt/Adobe AIR/Versions/1.0/Resources/libcurl.so to use relocation as a
workaround, until the library is fixed. Please file a bug report.

Allowing Access:

If you trust /opt/Adobe AIR/Versions/1.0/Resources/libcurl.so to run correctly,
you can change the file context to textrel_shlib_t. "chcon -t textrel_shlib_t
'/opt/Adobe AIR/Versions/1.0/Resources/libcurl.so'" You must also change the
default file context files on the system in order to preserve them even on a
full relabel. "semanage fcontext -a -t textrel_shlib_t
'/opt/Adobe.AIR/Versions/1.0/Resources/libcurl.so'"

Fix Command:

chcon -t textrel_shlib_t '/opt/Adobe AIR/Versions/1.0/Resources/libcurl.so'
