{"schemaVersion":3,"id":"SUSE-SU-2026:22574-1","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Security update for clamav\n\nThis update for clamav fixes the following issues:\n\nUpdate to version 1.5.3.\n\nSecurity issues fixed:\n\n- CVE-2026-20213: out-of-bounds write due to improper boundary checks for content in PE files during scanning\n  (bsc#1270107).\n- CVE-2026-20214: out-of-bounds write due to improper boundary checks for content in FSG files during scanning\n  (bsc#1270085).\n- CVE-2026-20215: out-of-bounds write due to improper boundary checks for content in 7z files during scanning\n  (bsc#1270088).\n- CVE-2026-20216: denial of service due to improper handling of temporary resources during InstallShield file scanning\n  (bsc#1270089).\n- CVE-2026-20217: out-of-bounds write due to improper boundary checks for content in PESpin files during scanning\n  (bsc#1270091).\n- CVE-2026-20243: out-of-bounds write due to improper boundary checks for content in ALZ files during scanning\n  (bsc#1270092).\n- CVE-2026-20244: integer overflow and DoS due to improper boundary checks for content in DMG files during scanning\n  (bsc#1270106).\n- CVE-2026-41676: buffer overflow due to missing checks via `Deriver:derive`, `PkeyCtxRef:derive` and OpenSSL 1.1.1\n  (bsc#1270138).\n\nOther updates and bugfixes:\n\n- Version 1.5.3:\n * Fixed a bug in the PESpin unpacker cleanup path that could free pointers into the scanned file buffer and crash the\n   scanner.\n * Fixed an integer overflow in PE rebuild size calculations that could be reached through a malformed Aspack-packed PE\n   file and lead to a heap buffer overflow write.\n * Fixed an InstallShield archive extraction limit bypass that could write far more temporary data than intended and\n   exhaust temporary storage.\n * Fixed an FSG unpacker loop underflow that could write past the section array while scanning a malformed PE file.\n * Fixed ALZ parser size handling bugs that could cause malformed ALZ archives to panic, abort the scanner, or skip\n   expected scan-limit handling.\n * Fixed a 7z parser substream count overflow that could under-allocate parser metadata arrays and write past them\n   while reading a malformed archive.\n * Fixed 32-bit DMG parser size checks that could let a short mish stripe table pass validation and crash 32-bit\n   scanner builds.\n * Hardened clamscan, clamdscan, and clamonacc quarantine actions against time-of-check/time-of-use races that could\n   redirect copied, moved, or removed files under unsafe quarantine directory configurations.\n * Upgraded the Rust tar dependency to resolve the RUSTSEC-2026-0067 and RUSTSEC-2026-0068 advisories, and upgraded the\n   Rust openssl dependency to resolve CVE-2026-41676.\n * Raised the minimum required CMake version to 3.17 to fix Linux builds with libcurl v8.21.0 when linking static\n   library dependencies.\n * Metadata preclass scans now run before the final scan verdict.\n * ClamOnAcc: Fixed errors when recursively excluded paths are children of an included path.\n * ClamOnAcc: Fixed hash bucket list corruption when two watched paths collide in the same bucket.","dates":{"published":"2026-07-07T16:57:40.000Z","modified":"2026-07-15T18:24:12.330Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":null,"severity":"unknown","version":null,"versionLabel":null,"source":null,"vector":null,"computed":false,"selection":"none"},"metrics":[]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[],"affected":[{"vendor":"suse","product":"clamav&distro=SUSE
