Alpine: botan: security update to 2.19.5-r0
medium Tenable Cloud Security Plugin ID 408533
Description
There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:- Botan is a C++ cryptography library. X.509 certificates can identify elliptic curves using either an
object identifier or using explicit encoding of the parameters. Prior to 3.5.0 and 2.19.5, checking name
constraints in X.509 certificates is quadratic in the number of names and name constraints. An attacker
who presented a certificate chain which contained a very large number of names in the
SubjectAlternativeName, signed by a CA certificate which contained a large number of name constraints,
could cause a denial of service. The problem has been addressed in Botan 3.5.0 and a partial backport has
also been applied and is included in Botan 2.19.5. (CVE-2024-34702)
- Botan is a C++ cryptography library. X.509 certificates can identify elliptic curves using either an
object identifier or using explicit encoding of the parameters. Prior to versions 3.3.0 and 2.19.4, an
attacker could present an ECDSA X.509 certificate using explicit encoding where the parameters are very
large. The proof of concept used a 16Kbit prime for this purpose. When parsing, the parameter is checked
to be prime, causing excessive computation. This was patched in 2.19.4 and 3.3.0 to allow the prime
parameter of the elliptic curve to be at most 521 bits. No known workarounds are available. Note that
support for explicit encoding of elliptic curve parameters is deprecated in Botan. (CVE-2024-34703)
- Botan is a C++ cryptography library. X.509 certificates can identify elliptic curves using either an
object identifier or using explicit encoding of the parameters. A bug in the parsing of name constraint
extensions in X.509 certificates meant that if the extension included both permitted subtrees and excluded
subtrees, only the permitted subtree would be checked. If a certificate included a name which was
permitted by the permitted subtree but also excluded by excluded subtree, it would be accepted. Fixed in
versions 3.5.0 and 2.19.5. (CVE-2024-39312)
