Beschreibung

This update for perl-YAML-Syck fixes the following issues: Changes in perl-YAML-Syck: - updated to 1.470.0 (1.47) [Security] - Fix four libsyck memory-safety CVEs reachable from the default YAML::Syck::Load() path on untrusted input with no special flags (reported by Paul Johnson via CPANSec, PR #213): - CVE-2026-57075 (CWE-125): out-of-bounds read in the base64 decoder caused by signed-char indexing of the decode table on !!binary input bsc#1271632 - CVE-2026-57076 (CWE-416): use-after-free of an anchor key string shared between the node and the anchors table bsc#1271633 - CVE-2026-57077 (CWE-125): one-byte out-of-bounds read in the lexer newline scan during block-scalar parsing (incomplete-fix follow-on to CVE-2025-11683) bsc#1271634 - CVE-2026-13713 (CWE-416/CWE-415): use-after-free / double-free of an anchor node on anchor redefinition, a remote-crash DoS from a 7-byte input bsc#1271631 - Harden syck_base64dec() to bounds-check each read so it cannot run past a non-NUL-terminated input buffer (defense-in-depth for callers passing raw buffers; PR #213) [Bug Fixes] - Fix: enforce $MaxDepth on Load to prevent C-stack exhaustion from deeply nested YAML/JSON input; YAML::Syck and JSON::Syck Load now default to 512, matching Dump (PR #204) - Fix: emit YAML canonical forms (.nan, .inf, -.inf) for NaN/Inf values in Dump so they roundtrip with ImplicitTyping instead of reloading as plain strings (PR #201) [Maintenance] - CI: add an AddressSanitizer job that builds the XS with -fsanitize=address and runs the suite plus the CVE trigger inputs to catch libsyck memory-safety defects; de-pin the libasan version so it tracks the runner's GCC (PR #213) - updated to 1.460.0 (1.46) [Bug Fixes] - Fix: preserve string nature of numeric-looking values in Dump; pure strings (POK only, no IOK/NOK) are now quoted to maintain roundtrip fidelity (GH #199, PR #200) - Fix: accept trailing commas in flow sequences and mappings ([a, b,] and {a: 1,}), valid per YAML 1.0/1.1/1.2 spec (GH #195, PR #196) [Maintenance] - CI: upgrade install-with-cpm to v2 for compatibility with Perl versions prior to 5.24 in perldocker containers (GH #197, PR #198) - Clean up MANIFEST.SKIP: add #!include_default, remove redundant entries, exclude .claude/ from distribution
