A specially crafted IPv4 packet, containing invalid encoded SSRR/LSRR options, may cause call-stack overflow. No specific services beyond IPv4 protocol support is required. Not affected by user-application code, this vulnerability resides in the IPv4 option parsing and may be triggered by IPv4 packets containing invalid options. The most likely outcome of triggering this defect is that the tNet0 task crashes. In the worst-case scenario, this vulnerability can potentially lead to RCE.

ASA-2019-00010 – systemd: Stack overflow when receiving many journald entries
An allocation of memory without limits, that could result in the stack clashing with another memory region, was discovered in systemd-journald when many entries are sent to the journal socket. A local attacker, or a remote one if systemd-journal-remote is used, may use this flaw to crash systemd-journald or execute code with journald privileges.
ASA-2019-00009 – systemd: Stack overflow when calling syslog from a command with long cmdline
An allocation of memory without limits, that could result in the stack clashing with another memory region, was discovered in systemd-journald when a program with long command line arguments calls syslog. A local attacker may use this flaw to crash systemd-journald or escalate his privileges.
