[ Impact ]
mirage is completely unusable as it will always segfault if any user tries to run the application.
Debugger showed that it is causing segfault when it is tryig to import the module xmouse. And then the coredump showed that the segfault is when Python is trying to check the flags for the methods while importing the module.
The upstream Python developers helped and the issue was found to be a missing sentinel value which caused "PyModule_Create" to access memory beyond the end of the array.
[ Test Plan ]
* Execute the command "mirage", which will segfault if its not fixed.
* With the fixed package, the "mirage" window will be displayed.
[ Where problems could occur ]
* This is not changing any part of the code and is only adding a sentinel value to terminate the array.
* It is already completely unusable for users, and this will not cause any more regression than what user experiences now.
[ Other Info ]
* All versions from Jammy are affected by this.
* More info at https://github.com/python/cpython/issues/113460

[ Impact ]
mirage is completely unusable as it will always segfault if any user tries to run the application.
Debugger showed that it is causing segfault when it is tryig to import the module xmouse. And then the coredump showed that the segfault is when Python is trying to check the flags for the methods while importing the module.
The upstream Python developers helped and the issue was found to be a missing sentinel value which caused "PyModule_Create" to access memory beyond the end of the array.
[ Test Plan ]
* Create an offline pcap file with the command:
printf '\xd4\xc3\xb2\xa1\x02\0\x04\0\0\0\0\0\0\0\0\0\0\0\x04\0\x01\0\0\0' > tmp.pcap
* Use the pcap file with sngrep with the command:
sngrep -I tmp.pcap
* The sngrep panel will be displayed.
* Press Esc key to exit, and then Enter to confirm.
* It will segfault if its not fixed.
* With the fixed package, the sngrep panel will exit without segfault.
[ Where problems could occur ]
* This is not changing any part of the code and is only adding a sentinel value to terminate the array.
* It is already completely unusable for users, and this will not cause any more regression than what user experiences now.
[ Other Info ]
* All versions from Jammy are affected by this.

[ Impact ]
mirage is completely unusable as it will always segfault if any user tries to run the application.
Debugger showed that it is causing segfault when it is tryig to import the module xmouse. And then the coredump showed that the segfault is when Python is trying to check the flags for the methods while importing the module.
The upstream Python developers helped and the issue was found to be a missing sentinel value which caused "PyModule_Create" to access memory beyond the end of the array.
[ Test Plan ]
* Execute the command "mirage", which will segfault if it's not fixed.
* With the fixed package, the "mirage" window will be displayed.
[ Where problems could occur ]
* This is not changing any part of the code and is only adding a sentinel value to terminate the array.
* It is already completely unusable for users, and this will not cause any more regression than what user experiences now.
[ Other Info ]
* All versions from Jammy are affected by this.
* More info at https://github.com/python/cpython/issues/113460
[ Original Bug Description ]
Newly installed mirage segfaults immediately when run.
