{"id":"UBUNTU-CVE-2026-121006","details":"HTTP::Body versions before 1.24_02 for Perl parse the trailer in quadratic time. Everything after the last chunk in the same call to add() is parsed with HTTP::Headers, which takes time quadratic in the number of fields of one name.  For example, it takes several seconds to parse 16 KiB of \"a:\" lines. A remote attackercan exhause the CPU with a single request. HTTP::Body version 1.25 limits the size and number of lines in the trailer.","modified":"2026-11-07T01:46:04.725764619Z","published":"2026-11-06T00:00:00Z","upstream":["CVE-2026-121006"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-121006"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-121006"},{"type":"REPORT","url":"https://lists.security.metacpan.org/cve-announce/msg/44934345/"},{"type":"REPORT","url":"https://github.com/libwww-perl/HTTP-Body/commit/983dd4ca3b863ab513240b02c91c3114fb299389.patch"},{"type":"REPORT","url":"https://metacpan.org/release/GETTY/HTTP-Body-1.24_02/changes"}],"affected":[{"package":{"name":"libhttp-body-perl","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/libhttp-body-perl?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.22-1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.22-1","binary_name":"libhttp-body-perl"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-121006.json"}},{"package":{"name":"libhttp-body-perl","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/libhttp-body-perl?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.22-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libhttp-body-perl","binary_version":"1.22-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-121006.json"}},{"package":{"name":"libhttp-body-perl","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/libhttp-body-perl?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.22-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libhttp-body-perl","binary_version":"1.22-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-121006.json"}},{"package":{"name":"libhttp-body-perl","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/libhttp-body-perl?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.22-1.1"],"ecosystem_specific":{"binaries":[{"binary_name":"libhttp-body-perl","binary_version":"1.22-1.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-121006.json"}},{"package":{"name":"libhttp-body-perl","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/libhttp-body-perl?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.22-2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.22-2","binary_name":"libhttp-body-perl"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-121006.json"}},{"package":{"name":"libhttp-body-perl","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/libhttp-body-perl?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.23-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libhttp-body-perl","binary_version":"1.23-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-121006.json"}},{"package":{"name":"libhttp-body-perl","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/libhttp-body-perl?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.23-1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.23-1","binary_name":"libhttp-body-perl"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-121006.json"}}],"schema_version":"1.9.2","severity":[{"type":"Ubuntu","score":"medium"}]}
