Successful exploitation could allow execution of arbitrary code on the affected machine. \n\n##### Vendor\n\nThe GNU Project - <https://www.gnu.org/software/barcode/> \nFree Software Foundation, Inc. - <https://directory.fsf.org/wiki/Barcode>\n\n##### Affected Version\n\n0.99 \n\n##### Tested On\n\nUbuntu 16.04.4 \n\n##### Vendor Status\n\n[09.12.2017] Vulnerability discovered. \n[14.05.2018] Vendor contacted. \n[28.05.2018] No response from the vendor. \n[29.05.2018] Public security advisory released. \n\n##### PoC\n\n[gnubarcode_bof.txt](<../../codes/gnubarcode_bof.txt>) \n[gnubarcode_crashes.tar](<../../codes/gnubarcode_crashes.tar>)\n\n##### Credits\n\nVulnerability discovered by Gjoko Krstic - &lt;[gjoko@zeroscience.mk](<mailto:gjoko@zeroscience.mk>)&gt;\n\n##### References\n\n[1] <https://www.exploit-db.com/exploits/44797/> \n[2] <https://cxsecurity.com/issue/WLB-2018050302> \n[3] <https://packetstormsecurity.com/files/147979> \n[4] <https://exchange.xforce.ibmcloud.com/vulnerabilities/144093>\n\n##### Changelog\n\n[29.05.2018] - Initial release \n[13.06.2018] - Added reference [2], [3] and [4] \n\n##### Contact\n\nZero Science Lab \n \nWeb: <http://www.zeroscience.mk> \ne-mail: [lab@zeroscience.mk](<mailto:lab@zeroscience.mk>)\n", "edition": 4, "enchantments": {"dependencies": {"modified": "2019-01-27T23:53:14", "references": [{"idList": ["OPENVAS:1361412562310107303"], "type": "openvas"}, {"idList": ["E-510", "E-564", "E-234"], "type": "dsquare"}]}, "score": {"modified": "2019-01-27T23:53:14", "value": 9.3, "vector": "NONE"}}, "hash": "581fd43b11bb79f8295f2438fb5372d0cb17b32a21b436e913ec6a5610cd6cfc", "hashmap": [{"hash": "c0f1c80b41d752feeb44eb576c63c7a6", "key": "sourceHref"}, {"hash": "708697c63f7eb369319c6523380bdf7a", "key": "bulletinFamily"}, {"hash": "65b9841e975b298f1cc686da2ba47411", "key": "description"}, {"hash": "d41d8cd98f00b204e9800998ecf8427e", "key": "references"}, {"hash": "d5a9f6a52710c9da60e2db94e75ccaf4", "key": "sourceData"}, {"hash": "8cdc434bfe47937b61b5842f9f82b1d2", "key": "published"}, {"hash": "d41d8cd98f00b204e9800998ecf8427e", "key": "cvelist"}, {"hash": "97c102c4d3d357f7349e7dba8a3d334f", "key": "href"}, {"hash": "8cd4821cb504d25572038ed182587d85", "key": "cvss"}, {"hash": "8ae079da90a361d7a0abdc807f4cd5a2", "key": "reporter"}, {"hash": "8cdc434bfe47937b61b5842f9f82b1d2", "key": "modified"}, {"hash": "edc9dc06a2dd9f6e2238c411ac8a6db8", "key": "type"}, {"hash": "a8299526ca2c6a72518d6c5bf3ac0947", "key": "title"}], "history": [], "href": "http://zeroscience.mk/en/vulnerabilities/ZSL-2018-5470.php", "id": "ZSL-2018-5470", "lastseen": "2019-01-27T23:53:14", "modified": "2018-05-29T00:00:00", "objectVersion": "1.3", "published": "2018-05-29T00:00:00", "references": [], "reporter": "Gjoko Krstic", "sourceData": "REQUEST LIMIT REACHED", "sourceHref": "http://zeroscience.mk/en/vulnerabilities/../../codes/gnubarcode_bof.txt", "title": "GNU Barcode 0.99 Buffer Overflow", "type": "zeroscience", "viewCount": 512}, "differentElements": ["sourceData"], "edition": 4, "lastseen": "2019-01-27T23:53:14"}], "edition": 8, "hashmap": [{"key": "bulletinFamily", "hash": "708697c63f7eb369319c6523380bdf7a"}, {"key": "cvelist", "hash": "d41d8cd98f00b204e9800998ecf8427e"}, {"key": "cvss", "hash": "8cd4821cb504d25572038ed182587d85"}, {"key": "description", "hash": "65b9841e975b298f1cc686da2ba47411"}, {"key": "href", "hash": "97c102c4d3d357f7349e7dba8a3d334f"}, {"key": "modified", "hash": "8cdc434bfe47937b61b5842f9f82b1d2"}, {"key": "published", "hash": "8cdc434bfe47937b61b5842f9f82b1d2"}, {"key": "references", "hash": "d41d8cd98f00b204e9800998ecf8427e"}, {"key": "reporter", "hash": "8ae079da90a361d7a0abdc807f4cd5a2"}, {"key": "sourceData", "hash": "d5a9f6a52710c9da60e2db94e75ccaf4"}, {"key": "sourceHref", "hash": "c0f1c80b41d752feeb44eb576c63c7a6"}, {"key": "title", "hash": "a8299526ca2c6a72518d6c5bf3ac0947"}, {"key": "type", "hash": "edc9dc06a2dd9f6e2238c411ac8a6db8"}], "hash": "581fd43b11bb79f8295f2438fb5372d0cb17b32a21b436e913ec6a5610cd6cfc", "viewCount": 514, "enchantments": {"dependencies": {"references": [{"type": "dsquare", "idList": ["E-564", "E-510", "E-234"]}], "modified": "2019-03-20T18:09:50"}, "score": {"value": 6.5, "vector": "NONE", "modified": "2019-03-20T18:09:50"}, "vulnersScore": 6.5}, "objectVersion": "1.3", "sourceHref": "http://zeroscience.mk/en/vulnerabilities/../../codes/gnubarcode_bof.txt", "sourceData": "REQUEST LIMIT REACHED", "scheme": null}
