A flaw was reported in kernel TCP subsystem while calculating a packet round trip time, when a sysctl parameter (/proc/sys/net/ipv4/tcpminrttwlen) when is set wrongly. This causes an integer over flaw which can lead to a Denial Of Service (DOS) attack.

Additional Information: ----------------------- https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=19fad20d15a6494f47f85d869f00b11343ee5c78

Remedy

This flaw can be mitigated by setting the sysctl parameter (/proc/sys/net/ipv4/tcp_min_rtt_wlen) with 300 which means the packet time will not exceed more then 5 minutes and which should not cause an integer overflow.

In the Linux kernel before 5.0.3, a memory leak exits in hsrdevfinalize() in net/hsr/hsrdevice.c if hsraddport fails to add a port, which may cause denial of service, aka CID-6caabe7f197d.

An issue was discovered in getvdevportnodeinfo in arch/sparc/kernel/mdesc.c in the Linux kernel through 5.1.6. There is an unchecked kstrdupconst of nodeinfo->vdevport.name, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash).

GNU C Library could allow a remote attacker to execute arbitrary code on the system, caused by an out-of-bounds write in the ISO-2022-CN-EXT plugin. By sending specially crafted input, an attacker could exploit this vulnerability to overwrite critical data structures and execute arbitrary code on the system or cause the application to crash.

The NetApp HCI H610C, H615C and H610S Baseboard Management Controllers (BMC) are shipped with a documented default account and password that should be changed during the initial node setup. During upgrades to Element 11.8 and 12.0 or the Compute Firmware Bundle 12.2.92 the BMC account password on the H610C, H615C and H610S platforms is reset to the default documented value which could allow remote attackers to cause a Denial of Service (DoS).
