It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-57432 in the wild and no public exploit code.\n\nAffected product: perl:perl. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-57432/ (Markdown: https://insights.sbomify.com/CVE-2026-57432/index.md)","id":"CVE-2026-57432","markdown":"https://insights.sbomify.com/CVE-2026-57432/index.md","name":"CVE-2026-57432","record":{"aliases":["AZL-92297","CLSA-2026-1784531112","CLSA-2026-1787646574","DEBIAN-CVE-2026-57432","ECHO-af51-df70-c8c4","GHSA-5g35-5jrj-f39p","MINI-47cj-mj97-jh2m","MINI-8p26-5vq2-86q9","ROOT-OS-ALPINE-322-CVE-2026-57432","ROOT-OS-ALPINE-323-CVE-2026-57432","ROOT-OS-DEBIAN-11-CVE-2026-57432","UBUNTU-CVE-2026-57432"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Perl programming language","requires_auth":"none","summary":"An integer overflow in Perl's pack and unpack functions allows attackers to read heap memory out of bounds via crafted templates.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CPANSec","cpe":[{"product":"perl","vendor":"perl"}],"cvss":{"score":8.4,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"Perl versions before 5.40.5-RC1, from 5.41.0 before 5.42.3-RC1, from 5.43.0 before 5.43.11 have an integer overflow in S_measure_struct leading to an out-of-bounds heap read in pack and unpack.\n\nS_measure_struct adds each item's size times its repeat count to a running total with no overflow check, so a large repeat count in a pack or unpack template wraps the signed SSize_t total negative.
