{"id":"UBUNTU-CVE-2026-116735","details":"libpff through 20260926 contains an off-by-one bounds check in libpff_table_read_6c_record_entries that allows attackers to trigger a heap out-of-bounds read via crafted 6c table record entries. Attackers can supply crafted PST, OST or PAB files to applications like pffexport or pypff to read adjacent heap memory or cause crashes.","modified":"2026-10-28T20:17:45.938568086Z","published":"2026-10-26T22:16:00Z","upstream":["CVE-2026-116735"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-116735"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-116735"},{"type":"REPORT","url":"https://github.com/libyal/libpff"},{"type":"REPORT","url":"https://github.com/cveproject/cvelistv5/tree/main/cves/2026/116xxx/cve-2026-116735.json"},{"type":"REPORT","url":"https://github.com/libyal/libpff/blob/20260926/libpff/libpff_table.c#l5431-l5445"},{"type":"REPORT","url":"https://github.com/libyal/libpff/commit/cb83eb38ffdbdfe2c69238fe7ce481ddc8513266"},{"type":"REPORT","url":"https://github.com/libyal/libpff/issues/172"},{"type":"REPORT","url":"https://hackmd.io/@haindpwn/libpff-table-parsing-oob-reads"},{"type":"REPORT","url":"https://nvd.nist.gov/vuln/detail/cve-2026-116735"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/libpff-through-20260926-heap-out-of-bounds-read-via-libpff-table-read-6c-record-entries"}],"affected":[{"package":{"name":"libpff","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/libpff?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["20120802-5"],"ecosystem_specific":{"binaries":[{"binary_name":"libpff1","binary_version":"20120802-5"},{"binary_name":"pff-tools","binary_version":"20120802-5"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116735.json"}},{"package":{"name":"libpff","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/libpff?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["20120802-5","20120802-5.1"],"ecosystem_specific":{"binaries":[{"binary_name":"libpff1","binary_version":"20120802-5.1"},{"binary_name":"pff-tools","binary_version":"20120802-5.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116735.json"}},{"package":{"name":"libpff","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/libpff?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["20180714-1","20180714-2"],"ecosystem_specific":{"binaries":[{"binary_name":"libpff1","binary_version":"20180714-2"},{"binary_name":"pff-tools","binary_version":"20180714-2"},{"binary_name":"python3-pypff","binary_version":"20180714-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116735.json"}},{"package":{"name":"libpff","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/libpff?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["20180714-3","20180714-3build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libpff1","binary_version":"20180714-3build1"},{"binary_name":"pff-tools","binary_version":"20180714-3build1"},{"binary_name":"python3-pypff","binary_version":"20180714-3build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116735.json"}},{"package":{"name":"libpff","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/libpff?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["20180714-3build2","20180714-3build3","20180714-3.1","20180714-3.1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libpff1t64","binary_version":"20180714-3.1build1"},{"binary_name":"pff-tools","binary_version":"20180714-3.1build1"},{"binary_name":"python3-pypff","binary_version":"20180714-3.1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116735.json"}},{"package":{"name":"libpff","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/libpff?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["20231205-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libpff1t64","binary_version":"20231205-1build1"},{"binary_name":"pff-tools","binary_version":"20231205-1build1"},{"binary_name":"python3-pypff","binary_version":"20231205-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116735.json"}},{"package":{"name":"libpff","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/libpff?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["20180714-3.1build2","20231205-1","20231205-1build1"],"ecosystem_specific":{"binaries":[{"binary_version":"20231205-1build1","binary_name":"libpff1t64"},{"binary_name":"pff-tools","binary_version":"20231205-1build1"},{"binary_name":"python3-pypff","binary_version":"20231205-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security
