CVE-2026-58471 is fixed in 5 products on 1 platform, first by wget 1.25.0-2ubuntu4.2, released July 7, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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.
