#coordinated-disclosure
5 writeups.
-
Three memory-safety bugs in libtsm's terminal escape-sequence parser — but the part worth remembering isn't the bugs, it's how a clean-gate target got chosen from a thin pool, and the moment the fork I fuzzed turned out to be the wrong place to send the report.
-
I reported four memory-safety bugs in zchunk privately; the same afternoon an independent contributor opened a public PR fixing one of them — but not its sibling. The part worth remembering is how a narrow fix leaves a matching hole one field over, and why reporting the whole cluster matters.
-
Client-side memory-safety bugs in libnfs and libsmb2 went nowhere for two weeks, then got fixed within hours of one follow-up — and the parts worth remembering are the disclosure mechanics and the two moments verification saved the report.
-
A malformed-input path in libebml's EBML reader was already guarded on the v1.x branch but never forward-ported to master — a look at the missing-backport bug class and being wrong about a PoC while still being useful.
