Description of problem: SELinux is preventing wine-preloader from using the 'execheap' accesses on a process. ***** Plugin allow_execheap (53.1 confidence) suggests ******************** Pokud nemáte za to, že by wine-preloader měl mít potřebu mapovat zásobník paměti (heap), který je zapisovatelný i spustitelný zároveň. Then měli byste nahlásit chybu. Toto je potenciálně nebezpečný přístup. Do kontaktujte bezpečnostního správce a nahlašte mu tento problém. ***** Plugin catchall_boolean (42.6 confidence) suggests ****************** Pokud chcete allow unconfined executables to make their heap memory executable. Doing this is a really bad idea. Probably indicates a badly coded executable, but could indicate an attack. This executable should be reported in bugzilla Then musíte o tomto SELinuxu říct povolením booleovské hodnoty „selinuxuser_execheap“. Do setsebool -P selinuxuser_execheap 1 ***** Plugin catchall (5.76 confidence) suggests ************************** Pokud jste přesvědčeni, že má wine-preloader mít ve výchozím stavu přístup execheap na procesy se značkou unconfined_t. Then měli byste tento problém nahlásit jako chybu. Abyste přístup povolili, můžete vygenerovat lokální modul pravidel. Do prozatím tento přístup povolíte příkazy: # ausearch -c 'wine-preloader' --raw | audit2allow -M my-winepreloader # semodule -X 300 -i my-winepreloader.pp Additional Information: Source Context unconfined_u:unconfined_r:unconfined_t:s0- s0:c0.c1023 Target Context unconfined_u:unconfined_r:unconfined_t:s0- s0:c0.c1023 Target Objects Neznámé [ process ] Source wine-preloader Source Path wine-preloader Port <Neznámé> Host (removed) Source RPM Packages Target RPM Packages SELinux Policy RPM selinux-policy-targeted-38.30-1.fc38.noarch Local Policy RPM selinux-policy-targeted-38.30-1.fc38.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 6.6.2-101.fc38.x86_64 #1 SMP PREEMPT_DYNAMIC Wed Nov 22 21:31:13 UTC 2023 x86_64 Alert Count 1 First Seen 2023-12-03 15:42:37 CET Last Seen 2023-12-03 15:42:37 CET Local ID 4b06d0e8-74ef-41bd-8816-b720c07e1297 Raw Audit Messages type=AVC msg=audit(1701614557.691:879): avc: denied { execheap } for pid=1119680 comm="wine-preloader" scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=process permissive=0 Hash: wine-preloader,unconfined_t,unconfined_t,process,execheap Version-Release number of selected component: selinux-policy-targeted-38.30-1.fc38.noarch Additional info: reporter: libreport-2.17.11 component: selinux-policy kernel: 6.6.2-101.fc38.x86_64 hashmarkername: setroubleshoot reason: SELinux is preventing wine-preloader from using the 'execheap' accesses on a process. package: selinux-policy-targeted-38.30-1.fc38.noarch type: libreport component: selinux-policy
