Alpine: multiple perl-crypt-openssl-x509 packages: security update to 2.1.3-r0

critical Tenable Cloud Security Plugin ID 445381

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

 - Crypt::OpenSSL::X509 versions before 2.1.3 for Perl allow denial of service via NULL pointer dereference.
 X509V3_EXT_d2i(ext) returns NULL when an extension's DER value fails to parse. basicC, ia5string, and
 auth_att dereference its result without a NULL check. keyid_data also dereferences akid->keyid, which is
 NULL for an empty AKI SEQUENCE (DER 30 00) even when the parse succeeds. A caller invoking an affected
 helper on an extension from an untrusted certificate triggers a SIGSEGV that crashes the Perl process.
 (CVE-2026-58101)

 - Crypt::OpenSSL::X509 versions before 2.1.3 for Perl allow a heap out-of-bounds read via a long certificate
 extension OID in hv_exts. When building the extension hash (via extensions(), extensions_by_long_name(),
 extensions_by_oid(), or has_extension_oid()), the code passes OBJ_obj2txt()'s return value as the hash-key
 length; because that value is the OID's full text length rather than the bytes written to the fixed-size
 buffer (129 bytes), an OID whose text is longer than the 129-byte buffer causes a read past the
 allocation, exposing adjacent heap memory as the returned hash key. extensions_by_name() uses the static
 shortname path and is not affected. (CVE-2026-58102)

Solution

Update the perl-crypt-openssl-x509 library and its related packages to version 2.1.3-r0 or later.
