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.

2 low-priority security issues in trixie low

There are 2 open security issues in trixie.

2 issues left for the package maintainer to handle:
  • CVE-2026-32877: (needs triaging) Botan is a C++ cryptography library. From version 2.3.0 to before version 3.11.0, during SM2 decryption, the code that checked the authentication code value (C3) failed to check that the encoded value was of the expected length prior to comparison. An invalid ciphertext can cause a heap over-read of up to 31 bytes, resulting in a crash or potentially other undefined behavior. This issue has been patched in version 3.11.0.
  • CVE-2026-32884: (needs triaging) Botan is a C++ cryptography library. Prior to version 3.11.0, during processing of an X.509 certificate path using name constraints which restrict the set of allowable DNS names, if no subject alternative name is defined in the end-entity certificate Botan would check that the CN was allowed by the DNS name constraints, even though this check is technically not required by RFC 5280. However this check failed to account for the possibility of a mixed-case CN. Thus a certificate with CN=Sub.EVIL.COM and no subject alternative name would bypasses an excludedSubtrees constraint for evil.com because the comparison is case-sensitive. This issue has been patched in version 3.11.0.

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