GNOME Bugzilla – Bug 532970
SELinux is preventing epiphany from changing the access protection of memory on the heap.
Last modified: 2008-05-23 21:24:40 UTC
Please describe the problem: The epiphany application attempted to change the access protection of memory on the heap (e.g., allocated using malloc). This is a potential security problem. Applications should not be doing this. Applications are sometimes coded incorrectly and request this permission. The SELinux Memory Protection Tests (http://people.redhat.com/drepper/selinux-mem.html) web page explains how to remove this requirement. If epiphany does not work and you need it to work, you can configure SELinux temporarily to allow this access until the application is fixed. Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package. Allowing Access: If you want epiphany to continue, you must turn on the allow_execheap boolean. Note: This boolean will affect all applications on the system. The following command will allow this access: setsebool -P allow_execheap=1 Additional Information: Source Context unconfined_u:system_r:unconfined_t:SystemLow- SystemHigh Target Context unconfined_u:system_r:unconfined_t:SystemLow- SystemHigh Target Objects None [ process ] Source epiphany Source Path /usr/bin/epiphany Port <Unknown> Host thedude.lebowski Source RPM Packages epiphany-2.20.3-4.fc8 Target RPM Packages Policy RPM selinux-policy-3.0.8-101.fc8 Selinux Enabled True Policy Type targeted MLS Enabled True Enforcing Mode Enforcing Plugin Name allow_execheap Host Name thedude.lebowski Platform Linux thedude.lebowski 2.6.24.5-85.fc8 #1 SMP Sat Apr 19 12:39:34 EDT 2008 i686 i686 Alert Count 1 First Seen Wed 26 Mar 2008 03:57:20 AM EDT Last Seen Tue 13 May 2008 07:48:27 AM EDT Local ID 6c673953-f76c-44aa-9c85-f366003a4c9a Line Numbers Raw Audit Messages host=thedude.lebowski type=AVC msg=audit(1210679307.749:15): avc: denied { execheap } for pid=4153 comm="epiphany" scontext=unconfined_u:system_r:unconfined_t:s0-s0:c0.c1023 tcontext=unconfined_u:system_r:unconfined_t:s0-s0:c0.c1023 tclass=process host=thedude.lebowski type=SYSCALL msg=audit(1210679307.749:15): arch=40000003 syscall=125 success=no exit=-13 a0=8188000 a1=370000 a2=5 a3=bf969b60 items=0 ppid=1 pid=4153 auid=500 uid=500 gid=500 euid=500 suid=500 fsuid=500 egid=500 sgid=500 fsgid=500 tty=(none) comm="epiphany" exe="/usr/bin/epiphany" subj=unconfined_u:system_r:unconfined_t:s0-s0:c0.c1023 key=(null) Steps to reproduce: 1. see above 2. 3.

That's gecko doing it (or a plugin).
