In version 1.0.0, OpenVM is vulnerable to overflow through byte decomposition of pc in AUIPC chip. A typo results in the highest limb of pc being range checked to 8-bits instead of 6-bits. This results in the if statement never being triggered because the enumeration gives i=0,1,2, when instead the enumeration should give i=1,2,3, leaving pc_limbs[3] range checked to 8-bits instead of 6-bits. This leads to a vulnerability where the pc_limbs decomposition differs from the true pc, which means a malicious prover can make the destination register take a different value than the AUIPC instruction dictates, by making the decomposition overflow the BabyBear field. This issue has been patched in version 1.1.0.\n\ud83d\udccf Published: 2025-05-02T22:18:55.696Z\n\ud83d\udccf Modified: 2025-05-02T22:18:55.696Z\n\ud83d\udd17 References:\n1. https://github.com/openvm-org/openvm/security/advisories/GHSA-jf2r-x3j4-23m7\n2. https://github.com/openvm-org/openvm/commit/68da4b50c033da5603517064aa0a08e1bbf70a01\n3. https://cantina.xyz/code/c486d600-bed0-4fc6-aed1-de759fd29fa2/findings/21\n4. https://github.com/openvm-org/openvm/blob/0f94c8a3dfa7536c1231465d1bdee5fc607a5993/extensions/rv32im/circuit/src/auipc/core.rs#L135\n5. https://github.com/openvm-org/openvm/releases/tag/v1.1.0", "creation_timestamp": "2025-05-02T23:17:25.000000Z"} 2025-05-02T23:17:25+00:00
