{"id":"UBUNTU-CVE-2006-10003","details":"XML::Parser versions through 2.47 for Perl has an off-by-one heap buffer overflow in st_serial_stack. In the case (stackptr == stacksize - 1), the stack will NOT be expanded. Then the new value will be written at location (++stackptr), which equals stacksize and therefore falls just outside the allocated buffer. The bug can be observed when parsing an XML file with very deep element nesting","modified":"2026-06-30T18:15:36.615526099Z","published":"2026-03-19T12:16:00Z","related":["USN-8174-1"],"upstream":["CVE-2006-10003"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2006-10003"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2006-10003"},{"type":"REPORT","url":"https://lists.security.metacpan.org/cve-announce/msg/38106362/"},{"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?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.41-3","2.44-1","2.44-1build1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.44-1build1","binary_name":"libxml-parser-perl"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2006/UBUNTU-CVE-2006-10003.json"}},{"package":{"name":"libxml-parser-perl","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/libxml-parser-perl?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-2006-10003.json"}},{"package":{"name":"libxml-parser-perl","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/libxml-parser-perl?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.44-4","2.44-4build1","2.46-1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.46-1","binary_name":"libxml-parser-perl"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2006/UBUNTU-CVE-2006-10003.json"}},{"package":{"name":"libxml-parser-perl","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/libxml-parser-perl?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":{"binaries":[{"binary_version":"2.46-3ubuntu0.1","binary_name":"libxml-parser-perl"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2006/UBUNTU-CVE-2006-10003.json"}},{"package":{"name":"libxml-parser-perl","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/libxml-parser-perl?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_version":"2.47-1ubuntu0.24.04.1","binary_name":"libxml-parser-perl"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2006/UBUNTU-CVE-2006-10003.json"}},{"package":{"name":"libxml-parser-perl","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/libxml-parser-perl?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.47-1ubuntu0.25.10.1"}]}],"versions":["2.47-1build4"],"ecosystem_specific":{"binaries":[{"binary_name":"libxml-parser-perl","binary_version":"2.47-1ubuntu0.25.10.1"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2006/UBUNTU-CVE-2006-10003.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:H/I:H/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/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"}]}
