An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-105842 in the wild and no public exploit code.\n\nAffected product: Uwe Ohse lrzsz. 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-2026-105842/ (Markdown: https://insights.sbomify.com/CVE-2026-105842/index.md)","id":"CVE-2026-105842","markdown":"https://insights.sbomify.com/CVE-2026-105842/index.md","name":"CVE-2026-105842","record":{"aliases":["AZL-106670","DEBIAN-CVE-2026-105842","GHSA-3cw3-cf87-8pwp","UBUNTU-CVE-2026-105842"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"ZMODEM file transfer utility","requires_auth":"none","summary":"A heap buffer overflow in lrzsz allows malicious ZMODEM senders to crash the application or potentially execute code via overlong filenames.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:L/VI:L/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"lrzsz before 0.13.0 contains a heap-based buffer overflow vulnerability in procheader() of the lrz receive utility when copying overlong sender-supplied filenames into Pathname.
