…H-95058) * syslog_get_argv() swallows exceptions, but not in all cases. * if ident is non UTF-8 encodable, syslog.openlog() fails after setting the global reference to ident. Now the C string saved internally in the previous call to openlog() points to the freed memory. * PySys_Audit() can crash if ident is NULL. * There may be a race condition with syslog.syslog(), because the global reference to ident is decrefed before setting the new value. * Possible use of freed memory if syslog.openlog() is called while the GIL is released in syslog.syslog().
