Selinux issues #74

Open LecrisUT opened 2 months ago

LecrisUT commented 2 months ago

I'm on Fedora 40 and I get the following selinux errors:

``` SELinux is preventing zulip from using the execheap access on a process. ***** Plugin allow_execheap (53.1 confidence) suggests ******************** If you do not think zulip should need to map heap 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 selinuxuser to execheap Then you must tell SELinux about this by enabling the 'selinuxuser_execheap' boolean. Do setsebool -P selinuxuser_execheap 1 ***** Plugin catchall (5.76 confidence) suggests ************************** If you believe that zulip should be allowed execheap 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: # ausearch -c 'zulip' --raw | audit2allow -M my-zulip # semodule -X 300 -i my-zulip.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 Unknown [ process ] Source zulip Source Path zulip Port Host cfelm-pcx33660 Source RPM Packages Target RPM Packages SELinux Policy RPM selinux-policy-targeted-40.23-1.fc40.noarch Local Policy RPM selinux-policy-targeted-40.23-1.fc40.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name cfelm-pcx33660 Platform Linux cfelm-pcx33660 6.9.8-200.fc40.x86_64 #1 SMP PREEMPT_DYNAMIC Fri Jul 5 16:20:11 UTC 2024 x86_64 Alert Count 15 First Seen 2024-07-12 11:32:08 CEST Last Seen 2024-07-12 11:34:27 CEST Local ID a8580292-d985-4e54-9e18-fb5cab54c960 Raw Audit Messages type=AVC msg=audit(1720776867.593:420): avc: denied { execheap } for pid=3195 comm="zulip" 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: zulip,unconfined_t,unconfined_t,process,execheap ```

Any ideas if this is an upstream issue or a flatpak packaging issue?
