erb is vulnerable to Integer Overflow
65
Medium Risk
This Affects:
erbTL;DR
Affected versions of this package are vulnerable to an integer overflow in the Util.html_escape method. The code stores segment lengths in a 16-bit integer (uint16_t), so a long unescaped segment (≥ 65,536 bytes) can wrap the length value, causing incorrect memcpy() sizes and a buffer overrun. This may lead to memory corruption and a crash (denial of service), and in the worst case could enable further exploitation.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
Background info
