Echo: wget: security update to 1.25.0-2+e3

medium Tenable Cloud Security Plugin ID 461748

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - GNU 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. This
 issue was fixed in commit e9697d98e7249b0f68a6be040a4f3dcc5bc101fa (CVE-2026-16599)

Solution

Update the wget library and its related packages to version 1.25.0-2+e3 or later.
