CVE-2018-1318
Adding method ACLs in remap.config can cause a segfault when the user makes a carefully crafted request.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (7.72%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Adding method ACLs in remap.config can cause a segfault when the user makes a carefully crafted request. This affects versions Apache Traffic Server (ATS) 6.0.0 to 6.2.2 and 7.0.0 to 7.1.3. To resolve this issue users running 6.x should upgrade to 6.2.3 or later versions and 7.x users should upgrade to 7.1.4 or later versions.
