An attacker can cause a Denial of Service (DoS) or potential information disclosure due to a use-after-free vulnerability, which occurs when a program reads memory that has already been released. This issue arises when the archive_entry_copy_mac_metadata() function deallocates an internal buffer before completing a data copy. An attacker who can supply input to an application utilizing this function can trigger the flaw to crash the application or read uninitialized memory data.(CVE-2026-17591)","modified":"2026-10-29T09:15:28.617871350Z","published":"2026-10-29T09:02:48Z","upstream":["CVE-2026-17591"],"database_specific":{"severity":"Low"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-4547"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-17591"}],"affected":[{"package":{"name":"libarchive","ecosystem":"openEuler:24.03-LTS-SP1","purl":"pkg:rpm/openEuler/libarchive&distro=openEuler-24.03-LTS-SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.7.1-14.oe2403sp1"}]}],"ecosystem_specific":{"aarch64":["bsdcat-3.7.1-14.oe2403sp1.aarch64.rpm","bsdcpio-3.7.1-14.oe2403sp1.aarch64.rpm","bsdtar-3.7.1-14.oe2403sp1.aarch64.rpm","bsdunzip-3.7.1-14.oe2403sp1.aarch64.rpm","libarchive-3.7.1-14.oe2403sp1.aarch64.rpm","libarchive-debuginfo-3.7.1-14.oe2403sp1.aarch64.rpm","libarchive-debugsource-3.7.1-14.oe2403sp1.aarch64.rpm","libarchive-devel-3.7.1-14.oe2403sp1.aarch64.rpm"],"noarch":["libarchive-help-3.7.1-14.oe2403sp1.noarch.rpm"],"src":["libarchive-3.7.1-14.oe2403sp1.src.rpm"],"x86_64":["bsdcat-3.7.1-14.oe2403sp1.x86_64.rpm","bsdcpio-3.7.1-14.oe2403sp1.x86_64.rpm","bsdtar-3.7.1-14.oe2403sp1.x86_64.rpm","bsdunzip-3.7.1-14.oe2403sp1.x86_64.rpm","libarchive-3.7.1-14.oe2403sp1.x86_64.rpm","libarchive-debuginfo-3.7.1-14.oe2403sp1.x86_64.rpm","libarchive-debugsource-3.7.1-14.oe2403sp1.x86_64.rpm","libarchive-devel-3.7.1-14.oe2403sp1.x86_64.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2026-4547.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:L"}]}
