{"id":"SUSE-SU-2026:3575-1","summary":"Security update for libarchive","details":"This update for libarchive fixes the following issues:\n\n- creating temporary files in the current working directory instead of the target directory can lead to file creation\n  failures when the working directory is not writable (bsc#1254340).\n- file descriptor leak in the mtree parser cleanup path could lead to file descriptor exhaustion and denial of service\n  (bsc#1261003).\n- NULL pointer dereference in archive_acl_from_text_w() could lead to a segmentation fault (bsc#1260998).\n- reading from an invalid index when buffer size is smaller than H_LEVEL_OFFSET can lead to an out-of-bounds buffer\n  overrun (bsc#1254341).\n- incorrect pointer handling for RAR5 files declaring over 8192 filters can lead to excessive resource usage and denial\n  of service (bsc#1261002).\n","modified":"2026-08-12T10:45:05.826894422Z","published":"2026-08-11T08:38:06Z","references":[{"type":"ADVISORY","url":"https://www.suse.com/support/update/announcement/2026/suse-su-20263575-1/"},{"type":"REPORT","url":"https://bugzilla.suse.com/1254340"},{"type":"REPORT","url":"https://bugzilla.suse.com/1254341"},{"type":"REPORT","url":"https://bugzilla.suse.com/1260998"},{"type":"REPORT","url":"https://bugzilla.suse.com/1261002"},{"type":"REPORT","url":"https://bugzilla.suse.com/1261003"}],"affected":[{"package":{"name":"libarchive","ecosystem":"SUSE:Linux Enterprise Micro 5.3","purl":"pkg:rpm/suse/libarchive&distro=SUSE%20Linux%20Enterprise%20Micro%205.3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.5.1-150400.3.27.1"}]}],"ecosystem_specific":{"binaries":[{"libarchive13":"3.5.1-150400.3.27.1"}]},"database_specific":{"source":"https://ftp.suse.com/pub/projects/security/osv/SUSE-SU-2026:3575-1.json"}},{"package":{"name":"libarchive","ecosystem":"SUSE:Linux Enterprise Micro 5.4","purl":"pkg:rpm/suse/libarchive&distro=SUSE%20Linux%20Enterprise%20Micro%205.4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.5.1-150400.3.27.1"}]}],"ecosystem_specific":{"binaries":[{"libarchive13":"3.5.1-150400.3.27.1"}]},"database_specific":{"source":"https://ftp.suse.com/pub/projects/security/osv/SUSE-SU-2026:3575-1.json"}},{"package":{"name":"libarchive","ecosystem":"SUSE:Linux Enterprise Micro 5.5","purl":"pkg:rpm/suse/libarchive&distro=SUSE%20Linux%20Enterprise%20Micro%205.5"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.5.1-150400.3.27.1"}]}],"ecosystem_specific":{"binaries":[{"libarchive13":"3.5.1-150400.3.27.1"}]},"database_specific":{"source":"https://ftp.suse.com/pub/projects/security/osv/SUSE-SU-2026:3575-1.json"}}],"schema_version":"1.9.0"}
