Security update for go1.26-openssl
This update for go1.26-openssl fixes the following issues:
Update to version 1.26.7 cut from the go1.25-fips-release branch at the revision tagged go1.26.7-1-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
resolvePathwhen 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
GOSUMDBis capable of serving arbitrary module content not contained within the transparency log (bsc#1275025). - CVE-2026-56865: x/mod/sumdb/tlog: a malicious
GOPROXYis capable of forging sumdb tiles, which allows for bypass of theGOSUMDBcheck and persistence of attacker-controlled module contents to a local Go module cache (bsc#1275024).

Описание
The ToASCII and ToUnicode functions incorrectly accept Punycode-encoded labels that decode to an ASCII-only label. For example, ToUnicode("xn--example-.com") incorrectly returns the name "example.com" rather than an error. This behavior can lead to privilege escalation in programs using the idna package. For example, a program which performs privilege checks on the ASCII hostname may reject "example.com" but permit "xn--example-.com". If that program subsequently converts the ASCII hostname to Unicode, it will inadvertently permits access to the Unicode name "example.com".

Описание
When a server is configured to support unencrypted HTTP/2, it reads a few bytes from each new connection to see if they contain the HTTP/2 client preface. ReadHeaderTimeout is unexpectedly not being applied when doing this.

Описание
Previously, resolving relative paths containing parent directory ('..') segments performed string conversions and buffer rewrites on each step, resulting in quadratic time complexity and high memory allocation overhead. Now, path resolution operates on a byte buffer using index-based backtracking for '..' segments, eliminating the quadratic time complexity and significantly reducing memory allocations.

Описание
Handshake messages, such as KeyUpdate, are always considered as state-advancing, regardless of whether a handshake has been completed or not. As a result, a malicious client can keep sending KeyUpdate messages to force the server to keep performing key derivation operations indefinitely.

Описание
A malicious GOSUMDB was capable of serving arbitrary module content not contained within the transparency log. This attack allows for a coordinating GOPROXY and GOSUMDB to serve a client malicious module content that cannot be detected by evaluating the transparency log. In order to determine if you have been affected: rm -r go.sum go.work.sum vendor/ && go mod tidy

Описание
A malicious GOPROXY was previously capable of forging up to two sumdb tiles that allow for a requested module to bypass the GOSUMDB check and persist attacker-controlled module content to a local Go module cache. This attack allows for a malicious GOPROXY to serve malicious module content that cannot be detected by evaluating the transparency log. All tiles are now correctly verified against their parents. In order to determine if you have been affected: rm -r go.sum go.work.sum vendor/ && go mod tidy
