TITLE

FreeBSD  Vulnerabilities in the use of freed memory

DESCRIPTION

In FreeBSD 12.1-STABLE before r364644, 11.4-STABLE before r364651, 12.1-RELEASE before p9, 11.4-RELEASE before p3, and 11.3-RELEASE before p13, improper handling in the kernel causes a use-after-free bug by sending large user messages from multiple threads on the same SCTP socket. The use-after-free situation may result in unintended kernel behaviour including a kernel panic. FreeBSD Is vulnerable to the use of freed memory.Denial of service (DoS) It may be put into a state. Pillow is a Python-based image processing library. There is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements. FreeBSD is a Unix-like operating system of the FreeBSD Foundation. FreeBSD has a buffer overflow vulnerability that allows an attacker to trigger a denial of service and code execution through SCTP Sockets.
