Carefully crafted nefarious Configuration (.cf) files can be configured to run system commands similar to CVE-2018-11805. This issue is less stealthy and attempts to exploit the issue will throw warnings. Thanks to Damian Lukowski at credativ for reporting the issue ethically. With this bug unpatched, exploits can be injected in a number of scenarios though doing so remotely is difficult. In addition to upgrading to SA 3.4.4, we again recommend that users should only use update channels or 3rd party .cf files from trusted places.","severity":{"version":"3.1","score":8.1,"vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","level":"high","assessor":"primary","from":"nvd"},"epss":{"day":"2026-11-09","score":0.06464,"percentile":0.93785,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-78"],"published":"2020-01-30T17:38:42Z","modified":"2026-10-26T12:02:29Z","fixes":[{"ecosystem":"Alpine:v3.10","package":"spamassassin","fixed_in":["3.4.4-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.11","package":"spamassassin","fixed_in":["3.4.4-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.12","package":"spamassassin","fixed_in":["3.4.4-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.13","package":"spamassassin","fixed_in":["3.4.4-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.14","package":"spamassassin","fixed_in":["3.4.4-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.15","package":"spamassassin","fixed_in":["3.4.4-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.16","package":"spamassassin","fixed_in":["3.4.4-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.17","package":"spamassassin","fixed_in":["3.4.4-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.18","package":"spamassassin","fixed_in":["3.4.4-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.19","package":"spamassassin","fixed_in":["3.4.4-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.20","package":"spamassassin","fixed_in":["3.4.4-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.21","package":"spamassassin","fixed_in":["3.4.4-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.22","package":"spamassassin","fixed_in":["3.4.4-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.23","package":"spamassassin","fixed_in":["3.4.4-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.24","package":"spamassassin","fixed_in":["3.4.4-r0"],"sources":["osv"]},{"ecosystem":"Debian:12","package":"spamassassin","fixed_in":["3.4.4~rc1-1"],"sources":["osv"]},{"ecosystem":"Debian:13","package":"spamassassin","fixed_in":["3.4.4~rc1-1"],"sources":["osv"]},{"ecosystem":"Debian:14","package":"spamassassin","fixed_in":["3.4.4~rc1-1"],"sources":["osv"]},{"ecosystem":"Ubuntu:Pro:14.04:LTS","package":"spamassassin","fixed_in":["3.4.2-0ubuntu0.14.04.1+esm2"],"sources":["osv"]},{"ecosystem":"Ubuntu:16.04:LTS","package":"spamassassin","fixed_in":["3.4.2-0ubuntu0.16.04.3"],"sources":["osv"]},{"ecosystem":"Ubuntu:18.04:LTS","package":"spamassassin","fixed_in":["3.4.2-0ubuntu0.18.04.3"],"sources":["osv"]}],"affected":[{"source":"osv","ecosystem":"Alpine:v3.10","package":"spamassassin","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.4.4-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.11","package":"spamassassin","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.4.4-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.12","package":"spamassassin","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.4.4-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.13","package":"spamassassin","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.4.4-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.14","package":"spamassassin","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.4.4-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.15","package":"spamassassin","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.4.4-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.16","package":"spamassassin","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.4.4-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.17","package":"spamassassin","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.4.4-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.18","package":"spamassassin","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.4.4-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.19","package":"spamassassin","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.4.4-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.20","package":"spamassassin","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.4.4-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.21","package":"spamassassin","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.4.4-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.22","package":"spamassassin","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.4.4-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.23","package":"spamassassin","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.4.4-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.24","package":"spamassassin","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.4.4-r0"}]}]},{"source":"osv","ecosystem":"TuxCare:OracleLinux:6","package":"spamassassin","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.3.1-3.el6.tuxcare.els1"}]}],"bundled":2},{"source
