This update for go1.25-openssl fixes the following issues:

Update to version 1.25.14 cut from the go1.25-fips-release branch at the revision tagged go1.25.14-1-openssl-fips.

Security issues fixed:

• CVE-2026-33818: encoding/asn1: stack exhaustion when parsing deeply-nested, recursive structures can lead to denial of service (bsc#1275034).
• CVE-2026-39821: golang.org/x/net/idna: failure to reject ASCII-only Punycode-encoded labels allows for validation bypass and privilege escalation (bsc#1266609).
• CVE-2026-56853: net/http: first header read timeout not being applied when a server is configured to support unencrypted HTTP/2 allows for denial of service (bsc#1275028).
• CVE-2026-56858: html/template: wrong JavaScript regexp context tracking after top-level { can lead to XSS (bsc#1275033).
• CVE-2026-56859: encoding/xml: stack exhaustion due to recursion depth guard bypass during decoding operations can lead to denial of service (bsc#1275026).
• CVE-2026-56860: net/url: quadratic complexity in resolvePath when processing backtrack path elements can lead to denial of service (bsc#1275029).
• CVE-2026-56862: crypto/tls: handshake messages can bypass non-advancing record limit in TLS 1.3, which can lead to a denial of service (bsc#1275032).
• CVE-2026-56864: x/mod/sumdb: a malicious GOSUMDB is capable of serving arbitrary module content not contained within the transparency log (bsc#1275025).
• CVE-2026-56865: x/mod/sumdb/tlog: a malicious GOPROXY is capable of forging sumdb tiles, which allows for bypass of the GOSUMDB check and persistence of attacker-controlled module contents to a local Go module cache (bsc#1275024).
