Fedora Linux 9327 Published by

Fedora 42 and 43 just received a batch of security updates that target several core packages across both distributions. The rpki-client package moved to version 9.8 with improved crypto compatibility and fixes for certificate handling, while the X server jumped to 21.1.22 to patch five separate vulnerabilities. Developers also pushed flatpak-builder version 1.4.8 to resolve a dangerous path traversal flaw, and minetest reached release 5.15.2 after closing critical sandbox escape bugs that could allow unauthorized access.

Name : rpki-client
Product : Fedora 42
Version : 9.8
Release : 1.fc42
URL : https://www.rpki-client.org/
Summary : OpenBSD RPKI validator to support BGP Origin Validation
Description :
The OpenBSD rpki-client is a free, easy-to-use implementation of the
Resource Public Key Infrastructure (RPKI) for Relying Parties (RP) to
facilitate validation of the Route Origin of a BGP announcement. The
program queries the RPKI repository system, downloads and validates
Route Origin Authorisations (ROAs) and finally outputs Validated ROA
Payloads (VRPs) in the configuration format of OpenBGPD, BIRD, and
also as CSV or JSON objects for consumption by other routing stacks.

--------------------------------------------------------------------------------
Update Information:

rpki-client 9.8
Various refactoring for improved compatibility with various libcrypto
implementations and in CA/BGPsec certificate handling.
Fixed an accounting issue in HTTP gzip compression detection.
Added a warning in extra verbose mode (-vv) about standards non-compliant Issuer
and Subject ASN.1 string encodings.
Added a check for canonical encoding of ASPA eContent in alignment with draft-
ietf-sidrops-aspa-profile-22.
Ensure that a repository timeout correctly stops repository processing.
Fixed a defect in Canonical Cache Representation ROAIPAddressFamily sort order.
As a result, rpki-client 9.8 cannot parse rpki-client 9.7's .ccr files and vice
versa.
Fixed an issue in the parser for the locally configured constraints.
A malicious RRDP Publication Server can cause a NULL dereference.
A malicious RPKI Publication Server can cause an incorrect error exit.
