{"id":"DEBIAN-CVE-2026-58102","details":"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.","modified":"2026-09-14T17:03:21.259301502Z","published":"2026-07-13T23:16:47.127Z","upstream":["CVE-2026-58102"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-58102"}],"affected":[{"package":{"name":"libcrypt-openssl-x509-perl","ecosystem":"Debian:12","purl":"pkg:deb/debian/libcrypt-openssl-x509-perl?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.9.14-2","1.9.15-1","2.0.0+pristine-1","2.0.1-1","2.1.1-1","2.1.2-1","2.1.3-1","2.1.5-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-58102.json"}},{"package":{"name":"libcrypt-openssl-x509-perl","ecosystem":"Debian:13","purl":"pkg:deb/debian/libcrypt-openssl-x509-perl?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.0.1-1","2.1.1-1","2.1.2-1","2.1.3-1","2.1.5-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-58102.json"}},{"package":{"name":"libcrypt-openssl-x509-perl","ecosystem":"Debian:14","purl":"pkg:deb/debian/libcrypt-openssl-x509-perl?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.1.3-1"}]}],"versions":["2.0.1-1","2.1.1-1","2.1.2-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-58102.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H"}]}
