Summary: Original oss-fuzz report: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3727#c2 The minimized test case that causes this failure: 5b 5b 5b 3d 47 53 00 5b 3d 5d 5b 5d 0a [[[=GS.[=][]. Note the string "=GS\x00". The failure happens because the code is searching the string against an array of known collated names. "GS\x00" is a hit, but since len takes into account an extra NUL byte, indexing into cp->name[len] goes one byte past it's allocated memory. Fix this to use a strlen(cp->name) comparison to account for NUL bytes in the input.
