An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of openSUSE-SU-2026:20851-1 in the wild and no public exploit code.\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/openSUSE-SU-2026-20851-1/ (Markdown: https://insights.sbomify.com/openSUSE-SU-2026-20851-1/index.md)","id":"openSUSE-SU-2026:20851-1","markdown":"https://insights.sbomify.com/openSUSE-SU-2026-20851-1/index.md","name":"openSUSE-SU-2026:20851-1","record":{"aliases":[],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"SSH client","requires_auth":"none","summary":"PuTTY contains a double-free and crash in RSA/ECDSA handling, allowing remote attackers to cause denial of service or potentially execute code.","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 update for putty fixes the following issues:\n\nChanges in putty:\n\n- Update to release 0.84\n  * Fixed a remotely triggerable double-free in RSA key exchange.\n  * Fixed a remotely triggerable crash (assertion failure - program\n    termination) in NIST ECDSA signature verification.\n  * Fixed marking of Telnet and Rlogin session data with a trust\n    sigil after you authenticated to a proxy (possibly allowing a\n    server to spoof a repeat proxy password prompt).\n  * New ability to run a specified command before starting the\n    connection, e.g. to perform wake-on-LAN or a port knock.\n  * Display 'pre-edit text', showing the progress of using multiple\n    keystrokes to compose a single Unicode character.\n  * Improved support for to running the GUI tools on Wayland (fixed\n    startup issues and tuned performance).\n  * Configuring a SSH certificate authority used to fail unless you\n    manually made a config directory, now fixed.\n  * Fixed a spurious \"Network error: Socket is not connected\" when\n    authenticating to some HTTP proxies.","ecosystems":[],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":null,"headline":"Security update for putty","id":"openSUSE-SU-2026:20851-1","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":null,"packages":[],"products":null,"published":"2026-05-31","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"PuTTY contains a double-free and crash in RSA/ECDSA handling, allowing remote attackers to cause denial of service or potentially execute code.","url":"https://insights.sbomify.com/openSUSE-SU-2026-20851-1/"}
