{"id":"UBUNTU-CVE-2006-10002","details":"XML::Parser versions through 2.45 for Perl could overflow the pre-allocated buffer size cause a heap corruption (double free or corruption) and crashes. A :utf8 PerlIO layer, parse_stream() in Expat.xs could overflow the XML input buffer because Perl's read() returns decoded characters while SvPV() gives back multi-byte UTF-8 bytes that can exceed the pre-allocated buffer size. This can cause heap corruption (double free or corruption) and crashes.","modified":"2026-04-16T09:40:35.960201Z","published":"2026-03-19T12:16:00Z","related":["USN-8174-1"],"upstream":["CVE-2006-10002"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2006-10002"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2006-10002"},{"type":"REPORT","url":"https://lists.security.metacpan.org/cve-announce/msg/38106361/"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-8174-1"}],"affected":[{"package":{"name":"libxml-parser-perl","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/libxml-parser-perl@2.44-1build1?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.41-3","2.44-1","2.44-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libxml-parser-perl","binary_version":"2.44-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2006/UBUNTU-CVE-2006-10002.json"}},{"package":{"name":"libxml-parser-perl","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/libxml-parser-perl@2.44-2build3?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.44-2build3"],"ecosystem_specific":{"binaries":[{"binary_name":"libxml-parser-perl","binary_version":"2.44-2build3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2006/UBUNTU-CVE-2006-10002.json"}},{"package":{"name":"libxml-parser-perl","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/libxml-parser-perl@2.46-1?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.44-4","2.44-4build1","2.46-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libxml-parser-perl","binary_version":"2.46-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2006/UBUNTU-CVE-2006-10002.json"}},{"package":{"name":"libxml-parser-perl","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/libxml-parser-perl@2.46-3ubuntu0.1?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.46-3ubuntu0.1"}]}],"versions":["2.46-2","2.46-2build1","2.46-3","2.46-3build1"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"libxml-parser-perl","binary_version":"2.46-3ubuntu0.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2006/UBUNTU-CVE-2006-10002.json"}},{"package":{"name":"libxml-parser-perl","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/libxml-parser-perl@2.47-1ubuntu0.24.04.1?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.47-1ubuntu0.24.04.1"}]}],"versions":["2.46-4","2.47-1","2.47-1build1","2.47-1build2","2.47-1build3"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"libxml-parser-perl","binary_version":"2.47-1ubuntu0.24.04.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2006/UBUNTU-CVE-2006-10002.json"}},{"package":{"name":"libxml-parser-perl","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/libxml-parser-perl@2.47-1ubuntu0.25.10.1?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.47-1ubuntu0.25.10.1"}]}],"versions":["2.47-1build4"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_version":"2.47-1ubuntu0.25.10.1","binary_name":"libxml-parser-perl"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2006/UBUNTU-CVE-2006-10002.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
