SELinux is preventing /usr/bin/guvcview from using the 'execstack' accesses on a process. ***** Plugin allow_execstack (53.1 confidence) suggests ******************** If you do not think /usr/bin/guvcview should need to map stack memory that is both writable and executable. Then you need to report a bug. This is a potentially dangerous access. Do contact your security administrator and report this issue. ***** Plugin catchall_boolean (42.6 confidence) suggests ******************* If you want to allow unconfined executables to make their stack executable. This should never, ever be necessary. Probably indicates a badly coded executable, but could indicate an attack. This executable should be reported in bugzilla Then you must tell SELinux about this by enabling the 'allow_execstack' boolean. Do setsebool -P allow_execstack 1 ***** Plugin catchall (5.76 confidence) suggests *************************** If you believe that guvcview should be allowed execstack access on processes labeled unconfined_t by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # grep guvcview /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1 023 Target Context unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1 023 Target Objects Unknown [ process ] Source guvcview Source Path /usr/bin/guvcview Port <Unknown> Host (removed) Source RPM Packages guvcview-1.4.3-1.fc14 Target RPM Packages Policy RPM selinux-policy-3.9.7-20.fc14 Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 2.6.35.10-74.fc14.i686.PAE #1 SMP Thu Dec 23 16:10:47 UTC 2010 i686 i686 Alert Count 1 First Seen Sat 22 Jan 2011 11:03:46 PM CET Last Seen Sat 22 Jan 2011 11:03:46 PM CET Local ID ddb9eee0-6330-4710-9868-b3ad5ff3e076 Raw Audit Messages type=AVC msg=audit(1295733826.949:36927): avc: denied { execstack } for pid=19320 comm="guvcview" scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=process guvcview,unconfined_t,unconfined_t,process,execstack type=SYSCALL msg=audit(1295733826.949:36927): arch=i386 syscall=mprotect success=yes exit=0 a0=bfcb3000 a1=1000 a2=1000007 a3=bfcb1e84 items=0 ppid=1 pid=19320 auid=501 uid=501 gid=501 euid=501 suid=501 fsuid=501 egid=501 sgid=501 fsgid=501 tty=(none) ses=1 comm=guvcview exe=/usr/bin/guvcview subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 key=(null) guvcview,unconfined_t,unconfined_t,process,execstack #============= unconfined_t ============== #!!!!
