Summary
Creates and applies delta files between OCI image archives for bootc systems. Delta files are significantly smaller than full OCI archives because they exclude layers already present on the target system and use binary diffs (tar-diff) for changed layers.
Security Fix(es):
* encoding/asn1: golang: Go encoding/asn1: Denial of Service via excessive recursion in Unmarshal (CVE-2026-33818)
* crypto/tls: golang: crypto/tls: Denial of Service via multiple ECH outer extension references (CVE-2026-97031)
Bug Fix(es) and Enhancement(s):
* Update oci-delta to v0.3.1 for Rocky Linux 10.3.z async release (JIRA:Rocky Linux-290036)

Vulnerabilities 2
-
High 7.5
Enforce maximum recursion depth in encoding/asn1
Enforce a recursion limit in Unmarshal to prevent stack exhaustion when parsing deeply-nested, recursive structures.
-
High 7.5
Reject malformed ECH outer extension references in crypto/tls
Multiple ECH outer extension references are not permitted under RFC 9849; previously, a client could send a well-crafted packet that could trigger memory exhaustion in the server process by specifying multiple references. We now reject these as malformed and …
