{"id":"CVE-2026-30909","details":"Crypt::NaCl::Sodium versions through 2.002 for Perl has potential integer overflows.\n\nbin2hex, encrypt, aes256gcm_encrypt_afternm and seal functions do not check that output size will be less than SIZE_MAX, which could lead to integer wraparound causing an undersized output buffer.\n\nEncountering this issue is unlikely as the message length would need to be very large.\n\nFor bin2hex() the bin_len would have to be \u003e SIZE_MAX / 2 For encrypt() the msg_len would need to be \u003e SIZE_MAX - 16U For aes256gcm_encrypt_afternm() the msg_len would need to be \u003e SIZE_MAX - 16U For seal() the enc_len would need to be \u003e SIZE_MAX - 64U","modified":"2026-04-02T13:23:40.375618Z","published":"2026-03-08T01:15:49.387Z","references":[{"type":"WEB","url":"https://metacpan.org/release/TIMLEGGE/Crypt-NaCl-Sodium-2.002/source/Sodium.xs#L2310"},{"type":"WEB","url":"https://metacpan.org/release/TIMLEGGE/Crypt-NaCl-Sodium-2.002/source/Sodium.xs#L3304"},{"type":"WEB","url":"https://metacpan.org/release/TIMLEGGE/Crypt-NaCl-Sodium-2.002/source/Sodium.xs#L942"},{"type":"WEB","url":"https://metacpan.org/release/TIMLEGGE/Crypt-NaCl-Sodium-2.002/source/Sodium.xs#L2116"},{"type":"ADVISORY","url":"https://metacpan.org/release/TIMLEGGE/Crypt-NaCl-Sodium-2.003/source/Changes"},{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2026/03/08/1"},{"type":"FIX","url":"https://github.com/cpan-authors/crypt-nacl-sodium/pull/24.patch"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/cpan-authors/crypt-nacl-sodium","events":[{"introduced":"0"},{"fixed":"73bb6df47f6a8cc6955b1c3cdf8c6ac0c74dd686"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"2.003"}]}}],"versions":["2.000","2.001","2.002","v0.01","v0.02","v0.03","v0.04","v0.05","v0.06","v0.07","v0.08","v0.09","v1.0.6.0","v1.0.6.1","v1.0.7.0","v1.0.8.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-30909.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
