Package: libfyaml0 Version: 0.8-1+b2 Severity: serious Tags: upstream Hi! The version of libfyaml in Debian contains a pretty nasty bug that destroys some UTF-8 characters and, if that ends in a null-byte, even ends streaming data entirely for a specific YAML value. This affects AppStream in Debian and on Debian's servers, so upgrading this package would be very important.
I have not bisected which change exactly fixed this issue, because there have been many utf8-related changes in libfyaml 0.9. However, I would bet that it's these two: https://github.com/pantoniou/libfyaml/commit/13d765ddcbea11c50d8fa5a4b2edb24ba2cc104a https://github.com/pantoniou/libfyaml/commit/a0b780ca24111bc8a7afcd0477e5559379bf69e2 It would be nice to get this fixed, as it yields pretty badly corrupted data. I have verified that libfyaml 0.9 indeed resolves the issue.
