Name of the Vulnerable Software and Affected Versions tcpdump versions prior to 4.9.2 Description The issue is related to a buffer over-read in the IP parser, specifically in the ip printts function within print-ip.c. Recommendations For versions prior to 4.9.2, update to version 4.9.2 or later t...

kernel: Double free in the inet_csk_clone_lock function in net/ipv4/inet_connection_sock.c

The inetcskclonelock function in net/ipv4/inetconnectionsock.c in the Linux kernel allows attackers to cause a denial of service double free or possibly have unspecified other impact by leveraging use of the accept system call. An unprivileged local user could use this flaw to induce kernel memor...

kernel: ipv4: Invalid IP options could cause skb->dst drop

A vulnerability was found in the Linux kernel where having malicious IP options present would cause the ipv4pktinfoprepare function to drop/free the dst. This could result in a system crash or possible privilege escalation...

UBUNTU-CVE-2017-3735

While parsing an IPAddressFamily extension in an X.509 certificate, it is possible to do a one-byte overread. This would result in an incorrect text display of the certificate. This bug has been present since 2006 and is present in all versions of OpenSSL before 1.0.2m and 1.1.0g...

kernel: l2tp: Race condition in the L2TPv3 IP encapsulation feature

A use-after-free flaw was found in the Linux kernel which enables a race condition in the L2TPv3 IP Encapsulation feature. A local user could use this flaw to escalate their privileges or crash the system...

kernel: net: IPv6 DCCP implementation mishandles inheritance

The IPv6 DCCP implementation in the Linux kernel mishandles inheritance, which allows local users to cause a denial of service or possibly have unspecified other impact via crafted system calls, a related issue to CVE-2017-8890. An unprivileged local user could use this flaw to induce kernel memo...

kernel: Incorrect overwrite check in __ip6_append_data()

The ip6appenddata function in net/ipv6/ip6output.c in the Linux kernel through 4.11.3 is too late in checking whether an overwrite of an skb data structure may occur, which allows local users to cause a denial of service system crash via crafted system calls...
