CVE-2006-0645: Tiny ASN.1 Library (libtasn1) before 0.2.18, as used by (1) GnuTLS 1.2.x before 1.2.10 and 1.3.x before 1.3...

Tiny ASN.1 Library (libtasn1) before 0.2.18, as used by (1) GnuTLS 1.2.x before 1.2.10 and 1.3.x before 1.3.4, and (2) GNU Shishi, allows attackers to crash the DER decoder and possibly execute arbitrary code via "out-of-bounds access" caused by invalid input, as demonstrated by the ProtoVer SSL test suite.

Security readout for executives and security teams

This is an old ASN.1 parsing flaw in libtasn1 that could let maliciously formed DER data crash software using the library, and possibly run code. It affected older GnuTLS and GNU Shishi deployments. Business urgency depends on whether legacy systems still carry these versions. Exposure is most plausible on legacy Linux or embedded systems using old libtasn1, GnuTLS, or GNU Shishi packages. Internet-facing TLS services and Kerberos-related components deserve priority review if they rely on affected library versions. Treat this as a legacy exposure cleanup item with high impact potential. It is not marked as actively exploited in the provided sources, but affected cryptographic and authentication components can sit in sensitive trust paths. Mitigation focus: Upgrade libtasn1 to 0.2.18 or later where affected.; Upgrade GnuTLS to 1.2.10, 1.3.4, or a vendor-fixed package.; Check vendor advisories for GNU Shishi package fixes..
