AlmaLinux 9.2 [TuxCare] Security Update: go-toolset / golang / golang-bin / golang-docs / golang-misc / etc Multiple Vulnerabilities (ALMALINUX9.2:CLSA-2026:1786527041)

medium Nessus Plugin ID 360010

Synopsis

The AlmaLinux host is missing one or more security updates.

Description

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1786527041 advisory.

 - Matching of hosts against proxy patterns can improperly treat an IPv6 zone ID as a hostname component. For example, when the NO_PROXY environment variable is set to *.example.com, a request to [::1%25.example.com]:80` will incorrectly match and not be proxied. (CVE-2025-22870)

 - The Parse function permits values other than IPv6 addresses to be included in square brackets within the host component of a URL. RFC 3986 permits IPv6 addresses to be included within the host component, enclosed within square brackets. For example: http://[::1]/. IPv4 addresses and hostnames must not appear within square brackets. Parse did not enforce this requirement. (CVE-2025-47912)

 - Parsing a maliciously crafted DER payload could allocate large amounts of memory, causing memory exhaustion. (CVE-2025-58185)

 - When Conn.Handshake fails during ALPN negotiation the error contains attacker controlled information (the ALPN protocols sent by the client) which is not escaped. (CVE-2025-58189)

 - The Reader.ReadResponse function constructs a response string through repeated string concatenation of lines. When the number of lines in a response is large, this can cause excessive CPU consumption.
 (CVE-2025-61724)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages based on the guidance in TuxCare advisory ALMALINUX9.2:CLSA-2026:1786527041.
