CVE-2017-7542 [MEDIUM] CWE-190 kernel: Integer overflow in ip6_find_1stfragopt() causes infinite loop
kernel: Integer overflow in ip6_find_1stfragopt() causes infinite loop
The ip6_find_1stfragopt function in net/ipv6/output_core.c in the Linux kernel through 4.12.3 allows local users to cause a denial of service (integer overflow and infinite loop) by leveraging the ability to open a raw socket.
An integer overflow vulnerability in ip6_find_1stfragopt() function was found. A local attacker that has privileges (of CAP_NET_RAW) to open raw socket can cause an infinite loop inside the ip6_find_1stfragopt() function.
Statement: This issue affects the Linux kernel packages as shipped with Red Hat Enterprise Linux 6, 7 and MRG-2. Future Linux kernel updates for the respective releases may address this issue.
