New, by me: Someone hacked into the Everest ransomware gang's dark web leak site and defaced it.

"Don't do crime CRIME IS BAD," Everest's site now reads.

It seems Budapest Micro Vol.2. was last weekend and the only info I can find about it is on the venue homepage and a report on scene.hu wtf?!

I wondered how OSS-Fuzz fuzzes Woff2 fonts with Brotli compression.

The answer seems to be… brute force.

https://issues.oss-fuzz.com/issues/42478986 shows a sample WOFF2 fuzzed font, and it contains a valid Brotli stream.

So oss-fuzz must be fuzzing raw WOFF2 fonts without a special mutator.

Yet it works: OSS-Fuzz coverage shows 93% coverage on the WOFF2 decoder:

It works, but the uncovered lines are the error lines… As if there’s not enough executions to actually hit the error cases…

looking at the execution coverage:

71.2k makes it to woff2_open_font 57.3k makes it to woff2_decompress 14.7k makes it to reconstruct_font 8.68k makes it to the end of woff2_open_font

(CVE-2025-3155) Arbitrary file read by abusing ghelp scheme

https://gitlab.gnome.org/GNOME/yelp/-/issues/221

"Yelp, the GNOME user help application, allows help documents to execute
arbitrary JavaScript. A malicious help document may exfiltrate user files
to a remote server. A malicious website may download a help document
without user intervention, then trick the user into opening a ghelp URL
that references the help document. This notably requires the attacker to
guess the filesystem path of the downloaded help document."
