Summary: SELinux is preventing /opt/TweetDeck/bin/TweetDeck from loading /opt/Adobe AIR/Versions/1.0/Resources/libcurl.so which requires text relocation. Detailed Description: [SELinux is in permissive mode. This access was not denied.] The TweetDeck 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' Additional Information: Source Context unconfined_u:unconfined_r:unconfined_execmem_t:s0- s0:c0.c1023 Target Context system_u:object_r:lib_t:s0 Target Objects /opt/Adobe AIR/Versions/1.0/Resources/libcurl.so [ file ] Source 41646F626520414952205570646174 Source Path /opt/Adobe AIR/Versions/1.0/Resources/Adobe AIR Updater Port <Unknown> Host (removed) Source RPM Packages tweetdeckfast.fff259dc0ce2657847bbb4aff0e62062efc5 6543.1-0.36.2-1 Target RPM Packages adobeair-2.5.1-17730 Policy RPM selinux-policy-3.7.19-69.fc13 Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Plugin Name allow_execmod Host Name (removed) Platform Linux (removed) 2.6.34.7-56.fc13.i686 #1 SMP Wed Sep 15 03:33:58 UTC 2010 i686 i686 Alert Count 7 First Seen Wed 27 Oct 2010 01:14:08 CEST Last Seen Sat 13 Nov 2010 23:54:34 CET Local ID 713864fa-4d0e-40b2-866a-d4f297c9e4e9 Line Numbers Raw Audit Messages node=(removed) type=AVC msg=audit(1289688874.734:24323): avc: denied { execmod } for pid=18601 comm="TweetDeck" path=2F6F70742F41646F6265204149522F56657273696F6E732F312E302F5265736F75726365732F6C69626375726C2E736F dev=dm-0 ino=393117 scontext=unconfined_u:unconfined_r:unconfined_execmem_t:s0-s0:c0.c1023 tcontext=system_u:object_r:lib_t:s0 tclass=file node=(removed) type=SYSCALL msg=audit(1289688874.734:24323): arch=40000003 syscall=125 success=yes exit=0 a0=6b4000 a1=13e000 a2=5 a3=bf84ea50 items=0 ppid=1 pid=18601 auid=500 uid=500 gid=500 euid=500 suid=500 fsuid=500 egid=500 sgid=500 fsgid=500 tty=(none) ses=4 comm="TweetDeck" exe="/opt/TweetDeck/bin/TweetDeck" subj=unconfined_u:unconfined_r:unconfined_execmem_t:s0-s0:c0.c1023 key=(null) Hash String generated from allow_execmod,41646F626520414952205570646174,unconfined_execmem_t,lib_t,file,execmod audit2allow suggests: #============= unconfined_execmem_t ============== #!!!!
