Summary
Stack overflow when parsing malicious DNS packet
Details

There's a stack overflow leading to a crash when Trust-DNS's parses a malicious DNS packet.

Affected versions of this crate did not properly handle parsing of DNS message compression (RFC1035 section 4.1.4). The parser could be tricked into infinite loop when a compression offset pointed back to the same domain name to be parsed.

This allows an attacker to craft a malicious DNS packet which when consumed with Trust-DNS could cause stack overflow and crash the affected software.

The flaw was corrected by trust-dns-proto 0.4.3 and upcoming 0.5.0 release.
