Overview
Affected versions of this package are vulnerable to Use of Uninitialized Variable in the ip6_tnl_parse_tlv_enc_lim function. An attacker can trigger the use of uninitialized memory by sending specially crafted IPv6 packets that cause the function to access insufficiently pulled data from the socket buffer.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
