[CLSA-2026:1793090437] alt-python310: Fix of CVE-2026-115557
Type:
security
Severity:
Critical
Release date:
2026-10-27 08:40:47 UTC
Description:
- CVE-2026-115557: reject TLS chains that use one of the compromised eMudhra intermediate CA keys. Backport of upstream gh-160040 / PR 160042, which shipped only in 3.11.18, 3.12.16, 3.13.18, 3.14.10 and 3.15.2; 3.10 is EOL upstream and got no release with it. Adds Modules/_ssl/distrusted_spki.h (verbatim from upstream) with the SHA-256 digests of the eight distrusted SubjectPublicKeyInfo structures, and an _ssl verify callback that fails the chain with X509_V_ERR_CERT_REJECTED when a certificate matches. Matching on the public key also covers cross-signed certificates that reuse one of the keys
