package is gone

This package is not in any development repository. This probably means that the package has been removed (or has been renamed). Thus the information here is of little interest ... the package is going to disappear unless someone takes it over and reintroduces it.

4 security issues in trixie high

There are 4 open security issues in trixie.

1 important issue:

CVE-2026-14570: Crypt::DSA versions before 1.22 for Perl draw the DSA signing nonce and private key from a biased random generator, leading to private-key recovery. "Crypt::DSA::Util::makerandom forces the high bit of every value it returns to obtain an exactly N-bit integer for prime search. The signing nonce and the private key are drawn from makerandom. Because the high bit is always set, the result is not uniform: its top bit is fixed, producing insecure values." An attacker who collects a modest number of signatures under an affected key, together with the public key, can recover the private key with a lattice attack. Keys used to sign with an affected version should be considered compromised and new keys should be generated.

2 issues left for the package maintainer to handle:

CVE-2026-8704: (needs triaging) Crypt::DSA versions through 1.19 for Perl use 2-args open, allowing existing files to be modified.
CVE-2026-12205: (needs triaging) Crypt::DSA versions before 1.21 for Perl reused the nonce across signatures, leading to private-key recovery. Crypt::DSA::sign caches the per-signature nonce material in the Key object without ever clearing it. The first sign() on a Key object picks a nonce, and every later sign() on that same object reuses it, producing an identical "r". Keys used to sign more than once with an affected version should be considered compromised.

You can find information about how to handle these issues in the security team's documentation.

1 ignored issue:

CVE-2026-8700: Crypt::DSA versions before 1.20 for Perl generate seeds using rand. Seeds were generated using Perl's built-in rand function, which is predictable and unsuitable for security usage.
