It was discovered that Wget mishandled semicolons in the userinfo
subcomponent of a URL. A remote attacker could possibly use this issue
to trick a user into connecting to a different host than intended. This
issue only affected Ubuntu 14.04 LTS. (CVE-2024-38428)
It was discovered that Wget incorrectly handled Metalink documents
containing a whitespace-only URL. A remote attacker could possibly use
this issue to cause a denial of service. This issue only affected Ubuntu
18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, and Ubuntu
26.04 LTS. (CVE-2026-58469)
It was discovered that Wget incorrectly handled Content-Range header
values, leading to an integer overflow. A remote attacker could
possibly use this issue to cause download desynchronization.
(CVE-2026-58470)
It was discovered that Wget incorrectly handled character set
conversion of server-supplied filenames. A remote attacker could possibly
use this issue to cause a denial of service or possibly execute arbitrary
code. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS,
Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, and Ubuntu 26.04 LTS. (CVE-2026-58471)
It was discovered that Wget incorrectly handled HTML attributes
requiring entity encoding. A remote attacker could possibly use this issue
to cause a denial of service or possibly execute arbitrary code.

Haruto Kimura discovered that GnuTLS did not properly apply permitted
name constraints in certain certificate validation paths. A remote
attacker could possibly use this issue to bypass certificate validation,
leading to a machine-in-the-middle attack. (CVE-2026-42011)
Oleh Konko discovered that GnuTLS incorrectly fell back to Common Name
checks for certain URI and SRV subject alternative names. A remote

Haruto Kimura and Joshua Rogers discovered that GnuTLS incorrectly fell
back to Common Name checks when subject alternative names were
oversized. A remote attacker could possibly use this issue to bypass
certificate validation, leading to a machine-in-the-middle attack.
(CVE-2026-42013)
Luigino Camastra and Joshua Rogers discovered that GnuTLS had a
use-after-free issue when changing PKCS#11 token security officer PINs
in certain cases. An attacker could possibly use this issue to cause

code. (CVE-2026-42014)
Zou Dikai discovered that GnuTLS did not properly validate PKCS#12 bag
sizes in certain cases. An attacker could possibly use this issue to
cause GnuTLS to crash, resulting in a denial of service, or execute
