CVE-2019-11366 severity moderate: SUSE including 3 source package names (atftp-0.7.0-135.16.16.3.1, atftp-0.7.0-135.23.3.1, atftp-0.7.0-160.8.1), 24 product×package rows across 24 product lines (SUSE Enterprise Storage 4, SUSE Linux Enterprise Desktop 12 SP3, … (24 product lines)): Fixed 24.
An issue was discovered in atftpd in atftp 0.7.1. It does not lock the thread_list_mutex mutex before assigning the current thread data structure. As a result, the daemon is vulnerable to a denial of service attack due to a NULL pointer dereference. If thread_data is NULL when assigned to current, and modified by another thread before a certain tftpd_list.c check, there is a crash when dereferencing current->next.
