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
