Prier to 1.4.2, there is a missing bounds check in Crypto_Key_update() (crypto_key_mgmt.c) which allows a remote attacker to trigger a stack-based buffer overflow by supplying a TLV packet with a spoofed length field. The function calculates the number of keys from an attacker-controlled field (pdu_len), which may exceed the static array size (kblk[98]), leading to an out-of-bounds write and potential memory corruption. This vulnerability is fixed in 1.4.2."}], "lastModified": "2025-11-11T01:53:25.467", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:nasa:cryptolib:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E4DDC475-C0F4-45E8-B998-99004402B827", "versionEndExcluding": "1.4.2"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
