However, this bug can be exploited in rare specific scenarios when monstart= up() and moncontrol() are called explicitly to collect statistics from a part of modules compiled with the corresponding options (nonetheless, I cannot disc= lose information about affected software either show the exploit). During submission for CVE-ID, I noted about that the bug could be exploited only when gmon activated, but such note is not included into CVE for now. --=20 You are receiving this mail because: You are on the CC list for the bug.=
