It can be exploited over the network, with no action from the victim.\nExploitation: There is no known exploitation of ALBA-2021:3050 in the wild and no public exploit code.\n\nAffected product: libsmbclient-devel. 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/ALBA-2021-3050/ (Markdown: https://insights.sbomify.com/ALBA-2021-3050/index.md)","id":"ALBA-2021:3050","markdown":"https://insights.sbomify.com/ALBA-2021-3050/index.md","name":"ALBA-2021:3050","record":{"aliases":[],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Samba file server","requires_auth":"unknown","summary":"A memory leak in the Samba RPC server can cause excessive memory allocation, potentially leading to denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"Samba is an open-source implementation of the Server Message Block (SMB)\nprotocol and the related Common Internet File System (CIFS) protocol, which\nallow PC-compatible machines to share files, printers, and various\ninformation.\n\nBug Fix(es) and Enhancement(s):\n\n* /sbin/ldconfig: /lib64/libsmbldap.so.2 is not a symbolic link\n(BZ#1964314)\n\n* smbd tries to delete files with wrong permissions (uses guest instead of\nuser from force user) (BZ#1964398)\n\n* Memory leak in RPC server could allocate a lot of memory for print\nservers (BZ#1969831)","ecosystems":["AlmaLinux:8"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":true,"headline":"samba bug fix and enhancement update","id":"ALBA-2021:3050","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":3,"n_references":null,"packages":[{"ecosystem":"AlmaLinux:8","fixed":["4.13.3-4.el8_4"],"introduced":["0"],"last_affected":[],"package":"libsmbclient-devel","purl":"pkg:rpm/almalinux/libsmbclient-devel","source":"ALBA-2021:3050"},{"ecosystem":"AlmaLinux:8","fixed":["4.13.3-4.el8_4"],"introduced":["0"],"last_affected":[],"package":"libwbclient-devel","purl":"pkg:rpm/almalinux/libwbclient-devel","source":"ALBA-2021:3050"},{"ecosystem":"AlmaLinux:8","fixed":["4.13.3-4.el8_4"],"introduced":["0"],"last_affected":[],"package":"samba-devel","purl":"pkg:rpm/almalinux/samba-devel","source":"ALBA-2021:3050"}],"products":null,"published":"2021-08-10","related":[],"sources":[{"class":"attribution","licence":"MIT","name":"AlmaLinux","prefix":"ALBA"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"A memory leak in the Samba RPC server can cause excessive memory allocation, potentially leading to denial of service.","url":"https://insights.sbomify.com/ALBA-2021-3050/"}
