{"id":"UBUNTU-CVE-2026-54633","details":"PoDoFo is a C++17 PDF manipulation library. From version 1.0.0 until 1.1.1, processing a crafted PDF with an Indexed color-space image can cause a heap out-of-bounds read in PdfColorSpaceFilterIndexed::FetchScanLine in src/podofo/main/PdfColorSpaceFilter.cpp. PODOFO_INVARIANT does not perform a runtime check, so a pixel index greater than or equal to m_MapSize can address beyond m_lookup. PdfColorSpaceFilterFactory::TryCreateFromObject also validates hival with an incorrect conjunction and no upper bound, allowing malformed Indexed color-space metadata outside the expected range. The resulting read can disclose adjacent heap data or crash the processing application. This issue is fixed in version 1.1.1.","modified":"2026-09-21T21:39:46.513951565Z","published":"2026-09-21T00:00:00Z","upstream":["CVE-2026-54633"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-54633"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-54633"},{"type":"REPORT","url":"https://github.com/podofo/podofo/security/advisories/GHSA-f3j2-7846-h5gg"},{"type":"REPORT","url":"https://github.com/podofo/podofo/commit/999c519d285c4a65eba48409d9cd2da9d4743cca"},{"type":"REPORT","url":"https://github.com/podofo/podofo/commit/999c519d285c4a65eba48409d9cd2da9d4743cca"},{"type":"REPORT","url":"https://github.com/podofo/podofo/releases/tag/1.1.1"}],"affected":[{"package":{"name":"libpodofo","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/libpodofo?arch=source&distro=esm-infra-legacy%2Ftrusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.9.0-1.1ubuntu1","0.9.0-1.2","0.9.0-1.2ubuntu0.1~esm1","0.9.0-1.2ubuntu0.1~esm3"],"ecosystem_specific":{"binaries":[{"binary_version":"0.9.0-1.2ubuntu0.1~esm3","binary_name":"libpodofo-utils"},{"binary_version":"0.9.0-1.2ubuntu0.1~esm3","binary_name":"libpodofo0.9.0"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54633.json"}},{"package":{"name":"libpodofo","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/libpodofo?arch=source&distro=esm-apps%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.9.0-1.3","0.9.3-3","0.9.3-4","0.9.3-4ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"libpodofo-utils","binary_version":"0.9.3-4ubuntu0.1~esm1"},{"binary_name":"libpodofo0.9.3","binary_version":"0.9.3-4ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54633.json"}},{"package":{"name":"libpodofo","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/libpodofo?arch=source&distro=esm-apps%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.9.5-6","0.9.5-8","0.9.5-8build1","0.9.5-9","0.9.5-9ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.9.5-9ubuntu0.1~esm1","binary_name":"libpodofo-utils"},{"binary_name":"libpodofo0.9.5","binary_version":"0.9.5-9ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54633.json"}},{"package":{"name":"libpodofo","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/libpodofo?arch=source&distro=esm-apps%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.9.6+dfsg-5","0.9.6+dfsg-5build1","0.9.6+dfsg-5ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.9.6+dfsg-5ubuntu0.1~esm1","binary_name":"libpodofo-utils"},{"binary_version":"0.9.6+dfsg-5ubuntu0.1~esm1","binary_name":"libpodofo0.9.6"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54633.json"}},{"package":{"name":"libpodofo","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/libpodofo?arch=source&distro=esm-apps%2Fjammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.9.7+dfsg-2","0.9.7+dfsg-2build1","0.9.7+dfsg-2build2","0.9.7+dfsg-3","0.9.7+dfsg-3ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"libpodofo-utils","binary_version":"0.9.7+dfsg-3ubuntu0.1~esm1"},{"binary_name":"libpodofo0.9.7","binary_version":"0.9.7+dfsg-3ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54633.json"}},{"package":{"name":"libpodofo","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/libpodofo?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.9.8+dfsg-3build1","0.9.8+dfsg-3build2","0.9.8+dfsg-3.1build1","0.9.8+dfsg-3.1build2","0.9.8+dfsg-3.1build3"],"ecosystem_specific":{"binaries":[{"binary_version":"0.9.8+dfsg-3.1build3","binary_name":"libpodofo-utils"},{"binary_version":"0.9.8+dfsg-3.1build3","binary_name":"libpodofo0.9.8t64"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54633.json"}},{"package":{"name":"libpodofo","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/libpodofo?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.9.8+dfsg-3.2","0.9.8+dfsg-3.3"],"ecosystem_specific":{"binaries":[{"binary_name":"libpodofo-utils","binary_version":"0.9.8+dfsg-3.3"},{"binary_version":"0.9.8+dfsg-3.3","binary_name":"libpodofo0.9.8t64"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54633.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"C
