hickory-proto is vulnerable to Denial of Service (DoS)
65
Medium Risk
This Affects:
hickory-protoTL;DR
The presentation-format parser for SVCB and HTTPS records mishandles a service parameter value that consists solely of a single quote character. It slices the value as if surrounding quotes were present, which panics on the malformed input. Systems that parse untrusted zone files can be crashed. The fix validates quoting before slicing.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you parse untrusted zone files
