A crafted input, i.e., crash report located in '/var/crash/', will lead to a denial of service attack. During the parsing of the crash report, the data length is not checked. The value of data length can be directly controlled by an input file. In the parse_report() function, the g_malloc or g_realloc is called based on data length. If we set the value of data length close to the amount of system memory, it will cause the daemon process to terminate unexpectedly, hang the system, or trigger the OOM killer. # PoC Please check the below whoopsie_killer2.py Sincerely, To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/whoopsie/+bug/1882180/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
