An update that solves two vulnerabilities and has three security fixes can now
be installed.

## Description:

This update for go1.25 fixes the following issues:

go1.25.5 (released 2025-12-02) includes two security fixes to the crypto/x509
package, as well as bug fixes to the mime and os packages. (bsc#1244485)

CVE-2025-61729 CVE-2025-61727:

  * go#76461 go#76445 bsc#1254431 security: fix CVE-2025-61729 crypto/x509:
    excessive resource consumption in printing error string for host certificate
    validation
  * go#76464 go#76442 bsc#1254430 security: fix CVE-2025-61727 crypto/x509:
    excluded subdomain constraint doesn't preclude wildcard SAN
  * go#76245 mime: FormatMediaType and ParseMediaType not compatible across 1.24
    to 1.25
  * go#76360 os: on windows RemoveAll removing directories containing read-only
    files errors with unlinkat ... Access is denied, ReOpenFile error handling
    followup

  * Packaging: Migrate from update-alternatives to libalternatives (bsc#1245878)

  * This is an optional migration controlled via prjconf definition
    with_libalternatives

  * If with_libalternatives is not defined packaging continues to use update-
    alternatives

go1.25.4 (released 2025-11-05) includes fixes to the compiler, the runtime, and
the crypto/subtle, encoding/pem, net/url, and os packages. (bsc#1244485)

  * go#75480 cmd/link: linker panic and relocation errors with complex generics
    inlining
  * go#75775 runtime: build fails when run via QEMU for linux/amd64 running on
    linux/arm64
  * go#75790 crypto/internal/fips140/subtle: Go 1.25 subtle.xorBytes panic on
    MIPS
  * go#75832 net/url: ipv4 mapped ipv6 addresses should be valid in square
    brackets
  * go#75952 encoding/pem: regression when decoding blocks with leading garbage
  * go#75989 os: on windows RemoveAll removing directories containing read-only
    files errors with unlinkat ... Access is denied
  * go#76010 cmd/compile: any(func(){})==any(func(){}) does not panic but should
  * go#76029 pem/encoding: malformed line endings can cause panics
