Description Quality Assurance univentionstaff 2019-05-13 09:29:42 CEST
New Debian atftp 0.7.git20120829-3.1~deb9u1 fixes:
This update addresses the following issues:
* An issue was discovered in atftpd in atftp 0.7.1. A remote attacker may  send a crafted packet triggering a stack-based buffer overflow due to an  insecurely implemented strncpy call. The vulnerability is triggered by  sending an error packet of 3 bytes or fewer. There are multiple instances  of this vulnerable strncpy pattern within the code base, specifically  within tftpd_file.c, tftp_file.c, tftpd_mtftp.c, and tftp_mtftp.c.  (CVE-2019-11365)
* 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. (CVE-2019-11366)
