Utorrent 1.6.1 !!better!! Page

| Risk Area | Severity | Description | | :--- | :--- | :--- | | | Critical | Multiple unpatched heap overflow vulnerabilities exist in the bdecode parser (CVE-2008-1326 variant). A malicious torrent file or DHT node could execute arbitrary code. | | HTTP Tracker Parsing | High | Stack buffer overflow in HTTP response handling (no ASLR/DEP mitigations on legacy binaries). | | Encryption | Low | Only supports Protocol Header Encryption (PE) – obsolete RC4-based. Does not support modern TLS 1.2+ for tracker announces. | | Third-party Libraries | Medium | Uses zlib 1.2.3 (2005 – known CVEs) and an internal SHA-1 implementation (collision-prone but irrelevant for torrent hashing). |
