CVE-2026-58102 (opens in a new tab)How to fix?
Upgrade Alpine:3.24 perl-crypt-openssl-x509 to version 2.1.3-r0 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream perl-crypt-openssl-x509 package and not the perl-crypt-openssl-x509 package as distributed by Alpine.
See How to fix? for Alpine:3.24 relevant fixed versions and status.
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.
