Podsumowanie: SELinux is preventing /opt/openoffice.org3/program/soffice.bin from making the program stack executable. Szczegółowy opis: [soffice.bin posiada typ zezwalania (unconfined_t). Ten dostęp nie został odmówiony.] The soffice.bin application attempted to make its stack executable. This is a potential security problem. This should never ever be necessary. Stack memory is not executable on most OSes these days and this will not change. Executable stack memory is one of the biggest security problems. An execstack error might in fact be most likely raised by malicious code. 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 soffice.bin 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. Zezwalanie na dostęp: Sometimes a library is accidentally marked with the execstack flag, if you find a library with this flag you can clear it with the execstack -c LIBRARY_PATH. Then retry your application. If the app continues to not work, you can turn the flag back on with execstack -s LIBRARY_PATH. Otherwise, if you trust soffice.bin to run correctly, you can change the context of the executable to execmem_exec_t. "chcon -t execmem_exec_t '/opt/openoffice.org3/program/soffice.bin'" 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 execmem_exec_t '/opt/openoffice.org3/program/soffice.bin'" Polecenie naprawy: chcon -t execmem_exec_t '/opt/openoffice.org3/program/soffice.bin' Dodatkowe informacje: Kontekst źródłowy unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1 023 Kontekst docelowy unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1 023 Obiekty docelowe None [ process ] Źródło soffice.bin Ścieżka źródłowa /opt/openoffice.org3/program/soffice.bin Port <Nieznane> Komputer (removed) Źródłowe pakiety RPM openoffice.org3-3.1.1-9420 Docelowe pakiety RPM Pakiet RPM polityki selinux-policy-3.6.32-49.fc12 SELinux jest włączony True Typ polityki targeted Tryb wymuszania Enforcing Nazwa wtyczki allow_execstack Nazwa komputera (removed) Platforma Linux (removed) 2.6.31.6-145.fc12.x86_64 #1 SMP Sat Nov 21 15:57:45 EST 2009 x86_64 x86_64 Liczba alarmów 37 Po raz pierwszy wto, 1 gru 2009, 15:47:24 Po raz ostatni śro, 2 gru 2009, 15:23:53 Lokalny identyfikator afffa564-65da-46c1-a5f0-7c368e1b421f Liczba wierszy Surowe komunikaty audytu node=(removed) type=AVC msg=audit(1259763833.161:23307): avc: denied { execstack } for pid=2181 comm="soffice.bin" scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=process node=(removed) type=SYSCALL msg=audit(1259763833.161:23307): arch=c000003e syscall=10 success=yes exit=4294967424 a0=7fff8f9ab000 a1=1000 a2=1000007 a3=38b8819aeb items=0 ppid=2144 pid=2181 auid=500 uid=500 gid=501 euid=500 suid=500 fsuid=500 egid=501 sgid=501 fsgid=501 tty=(none) ses=1 comm="soffice.bin" exe="/opt/openoffice.org3/program/soffice.bin" subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 key=(null) Hash String generated from selinux-policy-3.6.32-49.fc12,allow_execstack,soffice.bin,unconfined_t,unconfined_t,process,execstack audit2allow suggests: #============= unconfined_t ============== allow unconfined_t self:process execstack;
