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.

According to the versions of the wget packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    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.(CVE-2026-58471)

    GNU Wget through 1.25.0, fixed in commit 37a40fc, contains a heap buffer underread vulnerability in the     clean_metalink_string() function within src/metalink.c that allows a malicious server to trigger memory     corruption by serving a Metalink document containing a whitespace-only URL. Attackers can cause the     function to decrement a pointer past the start of the buffer when processing an all-whitespace Metalink     URL, potentially leading to abnormal program behavior.(CVE-2026-58469)

    GNU Wget through 1.25.0, fixed in commit dd692d9, contains a heap buffer overflow vulnerability in the     html_quote_string() function in src/convert.c that allows a remote attacker to trigger memory corruption     by supplying a crafted HTML attribute with a large number of characters requiring entity encoding. A     server-supplied HTML attribute causes a signed integer counter to overflow during output size     accumulation, resulting in an undersized heap allocation and subsequent heap buffer overflow during the     copy phase.(CVE-2026-58472)

    GNU Wget through 1.25.0, fixed in commit 43d3ba9, contains an integer overflow vulnerability in the     parse_content_range() function within src/http.c that allows server-controlled values to cause signed     integer arithmetic to overflow. Attackers can supply malicious Content-Range header values to trigger     undefined behavior and download desynchronization in the affected client.(CVE-2026-58470)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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. (CVE-2026-58471)

Note that Nessus relies on the presence of the package as reported by the vendor.
