{"id":"JLSEC-2026-1160","summary":"GNU Wget through 1.25.0, fixed in commit c2640fe, contains a heap buffer overflow vulnerability...","details":"GNU Wget through 1.25.0, fixed in commit c2640fe, contains a heap buffer overflow vulnerability in the `convert_fname()` function within `src/url.c` that allows remote attackers to trigger memory corruption through a server-supplied filename requiring character set conversion. When the output buffer is too small during iconv E2BIG reallocation, the reallocation logic miscalculates the remaining space, leading to a heap buffer overflow that can be exploited via a maliciously crafted server response.","modified":"2026-08-03T21:35:53.775390593Z","published":"2026-08-03T21:18:59.775Z","upstream":["CVE-2026-58471","EUVD-2026-42083","GHSA-vv88-699v-w5rh"],"database_specific":{"license":"CC-BY-4.0","sources":[{"published":"2026-07-07T21:17:28.710Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-58471","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58471","database_specific":{"status":"Analyzed"},"id":"CVE-2026-58471","imported":"2026-08-03T20:01:18.307Z","modified":"2026-07-09T16:02:07.273Z"},{"imported":"2026-08-03T20:01:21.687Z","modified":"2026-07-07T21:31:43Z","published":"2026-07-07T21:31:36Z","url":"https://api.github.com/advisories/GHSA-vv88-699v-w5rh","html_url":"https://github.com/advisories/GHSA-vv88-699v-w5rh","id":"GHSA-vv88-699v-w5rh"},{"id":"EUVD-2026-42083","imported":"2026-08-03T20:01:19.724Z","modified":"2026-07-14T22:03:12Z","published":"2026-07-07T19:47:47Z","url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-42083","html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-42083"}]},"references":[{"type":"WEB","url":"https://github.com/advisories/GHSA-vv88-699v-w5rh"},{"type":"WEB","url":"https://gitlab.com/gnuwget/wget/-/commit/c2640fe5171c59f87c58dc9fcb195b2d18b010ee"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58471"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/gnu-wget-heap-buffer-overflow-via-convert-fname-in-url-c"}],"affected":[{"package":{"name":"wget_jll","ecosystem":"Julia","purl":"pkg:julia/wget_jll?uuid=25883557-5102-5516-a11b-f84f27e871d7"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-1160.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:P/VC:N/VI:L/VA:H/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"}]}
