It is a non-interactive commandline tool, so it may easily be called from scripts, cron jobs, terminals without X-Windows support, etc.\r\n\r\nSecurity Fix(es):\n\nGNU wget is vulnerable to denial of service in its FTP OPIE/S-KEY authentication functionality. The server-supplied sequence number from the FTP challenge line is used as an iteration count for an MD5 key-derivation loop without any upper bound validation. A malicious FTP server or a network attacker positioned to intercept FTP traffic can send a crafted OPIE challenge with a sequence number near INT_MAX, causing wget to perform up to approximately 2.1 billion MD5 computations and suspend for some time. The --timeout option does not mitigate this because it applies only to network I/O, not CPU computation.(CVE-2026-16599)","affected":[{"package":{"ecosystem":"openEuler:20.03-LTS-SP4","name":"wget","purl":"pkg:rpm/openEuler/wget&distro=openEuler-20.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.20.3-8.oe2003sp4"}]}],"ecosystem_specific":{"aarch64":["wget-1.20.3-8.oe2003sp4.aarch64.rpm","wget-debuginfo-1.20.3-8.oe2003sp4.aarch64.rpm","wget-debugsource-1.20.3-8.oe2003sp4.aarch64.rpm","wget-help-1.20.3-8.oe2003sp4.aarch64.rpm"],"src":["wget-1.20.3-8.oe2003sp4.src.rpm"],"x86_64":["wget-1.20.3-8.oe2003sp4.x86_64.rpm","wget-debuginfo-1.20.3-8.oe2003sp4.x86_64.rpm","wget-debugsource-1.20.3-8.oe2003sp4.x86_64.rpm","wget-help-1.20.3-8.oe2003sp4.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-3766"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-16599"}],"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}],"database_specific":{"severity":"Medium"}}
