An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of GHSA-v8gq-5grq-9728 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mozjpeg (crates.io): affected all versions; fixed in 0.8.19\n- mozjpeg (crates.io): affected all versions; fixed in 0.8.19\n- mozjpeg (crates.io): affected from 0.0.0-0; fixed in 0.8.19\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/GHSA-v8gq-5grq-9728/ (Markdown: https://insights.sbomify.com/GHSA-v8gq-5grq-9728/index.md)","id":"GHSA-v8gq-5grq-9728","markdown":"https://insights.sbomify.com/GHSA-v8gq-5grq-9728/index.md","name":"GHSA-v8gq-5grq-9728","record":{"aliases":["RUSTSEC-2020-0165"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Rust image library","requires_auth":"none","summary":"Unsound memory handling in mozjpeg allows attackers to cause memory corruption or arbitrary code execution via crafted images.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"This issue and vector is similar to [RUSTSEC-2020-0029] of `rgb` crate which `mozjpeg` depends on.\n\nAffected versions of `mozjpeg` crate allow creating instances of any type `T` from bytes,\nand do not correctly constrain `T` to the types for which it is safe to do so.\n\nExamples of safety violation possible for a type `T`:\n\n* `T` contains a reference type, and it constructs a pointer to an invalid, arbitrary memory address.\n* `T` requires a safety and/or validity invariant for its construction that may be violated.\n\nThe issue was fixed in 0.8.19 by using safer types and involving `rgb` dependency bump.\n\n[RUSTSEC-2020-0029]: https://rustsec.org/advisories/RUSTSEC-2020-0029.html","ecosystems":["crates.io"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":true,"headline":"mozjpeg DecompressScanlines::read_scanlines is Unsound","id":"GHSA-v8gq-5grq-9728","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"crates.io","product":null,"products":[],"type":"memory_corruption","year":"2020"},"n_packages":3,"n_references":null,"packages":[{"ecosystem":"crates.io","fixed":["0.8.19"],"introduced":["0"],"last_affected":[],"package":"mozjpeg","purl":null,"source":"GHSA-v8gq-5grq-9728"},{"ecosystem":"crates.io","fixed":["0.8.19"],"introduced":["0"],"last_affected":[],"package":"mozjpeg","purl":"pkg:cargo/mozjpeg","source":"GHSA-v8gq-5grq-9728"},{"ecosystem":"crates.io","fixed":["0.8.19"],"introduced":["0.0.0-0"],"last_affected":[],"package":"mozjpeg","purl":"pkg:cargo/mozjpeg","source":"RUSTSEC-2020-0165"}],"products":null,"published":"2020-07-04","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"open","licence":"CC0 1.0","name":"RustSec","prefix":"RUSTSEC"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"Unsound memory handling in mozjpeg allows attackers to cause memory corruption or arbitrary code execution via crafted images.","url":"https://insights.sbomify.com/GHSA-v8gq-5grq-9728/"}
