Delegate » Delegate : Security Vulnerabilities, CVEs, Published In 2005

Multiple buffer overflows in DeleGate before 8.11.1 may allow attackers to cause a denial of service or execute arbitrary code, possibly due to "overflows on arrays."

The DNS implementation in DeleGate 8.10.2 and earlier allows remote attackers to cause a denial of service via a compressed DNS packet with a label length byte with an incorrect offset, which could trigger an infinite loop.
