{"id":"DEBIAN-CVE-2026-47729","details":"Squid is a caching proxy for the Web. Prior to 7.6, due to an improper validation of syntactic correctness of input in the FTP gateway (src/clients/FtpGateway.cc), Squid is vulnerable to an out-of-bounds read: when a listing entry date in the TypeA or TypeB directory-listing formats is not followed by a filename, parsing was not restricted to the input buffer, so a trusted client accessing a misbehaving FTP server through Squid's gateway feature could read memory from random unrelated transactions. This issue is fixed in version 7.6.","modified":"2026-09-14T17:03:15.703481492Z","published":"2026-07-16T17:16:57.217Z","upstream":["CVE-2026-47729"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-47729"}],"affected":[{"package":{"name":"squid","ecosystem":"Debian:12","purl":"pkg:deb/debian/squid?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.7-2+deb12u6"}]}],"versions":["5.7-2","5.7-2+deb12u1","5.7-2+deb12u2","5.7-2+deb12u3","5.7-2+deb12u4","5.7-2+deb12u5"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-47729.json"}},{"package":{"name":"squid","ecosystem":"Debian:13","purl":"pkg:deb/debian/squid?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.13-2+deb13u2"}]}],"versions":["6.13-2","6.13-2+deb13u1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-47729.json"}},{"package":{"name":"squid","ecosystem":"Debian:14","purl":"pkg:deb/debian/squid?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.6-1"}]}],"versions":["6.13-2","7.1-1","7.2-1","7.2-2","7.4-1","7.5-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-47729.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
