{"id":"ALPINE-CVE-2018-14938","details":"An issue was discovered in wifipcap/wifipcap.cpp in TCPFLOW through 1.5.0-alpha. There is an integer overflow in the function handle_prism during caplen processing. If the caplen is less than 144, one can cause an integer overflow in the function handle_80211, which will result in an out-of-bounds read and may allow access to sensitive memory (or a denial of service).","modified":"2025-12-03T22:45:58.781653Z","published":"2018-08-05T03:29:00.217Z","upstream":["CVE-2018-14938"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2018-14938"}],"affected":[{"package":{"name":"tcpflow","ecosystem":"Alpine:v3.11","purl":"pkg:apk/alpine/tcpflow?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.5.0-r0"}]}],"versions":["0.21-r0","0.21-r1","0.21-r2","1.2.8-r0","1.2.8-r1","1.2.9-r0","1.3.0-r0","1.4.4-r0","1.4.5-r0","1.4.5-r1","1.4.5-r2","1.4.5-r3","1.4.5-r4"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-14938.json"}},{"package":{"name":"tcpflow","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/tcpflow?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.5.0-r0"}]}],"versions":["0.21-r0","0.21-r1","0.21-r2","1.2.8-r0","1.2.8-r1","1.2.9-r0","1.3.0-r0","1.4.4-r0","1.4.5-r0","1.4.5-r1","1.4.5-r2","1.4.5-r3","1.4.5-r4"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-14938.json"}},{"package":{"name":"tcpflow","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/tcpflow?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.5.0-r0"}]}],"versions":["0.21-r0","0.21-r1","0.21-r2","1.2.8-r0","1.2.8-r1","1.2.9-r0","1.3.0-r0","1.4.4-r0","1.4.5-r0","1.4.5-r1","1.4.5-r2","1.4.5-r3","1.4.5-r4"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-14938.json"}},{"package":{"name":"tcpflow","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/tcpflow?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.5.0-r0"}]}],"versions":["0.21-r0","0.21-r1","0.21-r2","1.2.8-r0","1.2.8-r1","1.2.9-r0","1.3.0-r0","1.4.4-r0","1.4.5-r0","1.4.5-r1","1.4.5-r2","1.4.5-r3","1.4.5-r4"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-14938.json"}},{"package":{"name":"tcpflow","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/tcpflow?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.5.0-r0"}]}],"versions":["0.21-r0","0.21-r1","0.21-r2","1.2.8-r0","1.2.8-r1","1.2.9-r0","1.3.0-r0","1.4.4-r0","1.4.5-r0","1.4.5-r1","1.4.5-r2","1.4.5-r3","1.4.5-r4"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-14938.json"}},{"package":{"name":"tcpflow","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/tcpflow?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.5.0-r0"}]}],"versions":["0.21-r0","0.21-r1","0.21-r2","1.2.8-r0","1.2.8-r1","1.2.9-r0","1.3.0-r0","1.4.4-r0","1.4.5-r0","1.4.5-r1","1.4.5-r2","1.4.5-r3","1.4.5-r4"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-14938.json"}},{"package":{"name":"tcpflow","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/tcpflow?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.5.0-r0"}]}],"versions":["0.21-r0","0.21-r1","0.21-r2","1.2.8-r0","1.2.8-r1","1.2.9-r0","1.3.0-r0","1.4.4-r0","1.4.5-r0","1.4.5-r1","1.4.5-r2","1.4.5-r3","1.4.5-r4"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-14938.json"}},{"package":{"name":"tcpflow","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/tcpflow?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.5.0-r0"}]}],"versions":["0.21-r0","0.21-r1","0.21-r2","1.2.8-r0","1.2.8-r1","1.2.9-r0","1.3.0-r0","1.4.4-r0","1.4.5-r0","1.4.5-r1","1.4.5-r2","1.4.5-r3","1.4.5-r4"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-14938.json"}},{"package":{"name":"tcpflow","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/tcpflow?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.5.0-r0"}]}],"versions":["0.21-r0","0.21-r1","0.21-r2","1.2.8-r0","1.2.8-r1","1.2.9-r0","1.3.0-r0","1.4.4-r0","1.4.5-r0","1.4.5-r1","1.4.5-r2","1.4.5-r3","1.4.5-r4"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-14938.json"}},{"package":{"name":"tcpflow","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/tcpflow?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.5.0-r0"}]}],"versions":["0.21-r0","0.21-r1","0.21-r2","1.2.8-r0","1.2.8-r1","1.2.9-r0","1.3.0-r0","1.4.4-r0","1.4.5-r0","1.4.5-r1","1.4.5-r2","1.4.5-r3","1.4.5-r4"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-
