  3. I'm curious to know what people think about Anthropic's claim that Claude found 500 high-severity vulnerabilities in open-source packages.

    @dangoodin if "this commit changed a thing to fix a bug" is the metric, well fuck, I've found over 100,000 'vulnerabilities' in the past year.

    That's not what Antropic said. Antropic said the vulns were high-severity.

      @dangoodin that is EXACTLY what Anthropic said. LITERALLY it is the FIRST "vulnerability" they bogusly claim to have found.

      > Neither of these methods yielded any significant findings. Eventually, however, Claude took a different approach: reading the Git commit history. Claude quickly found a security-relevant commit, and commented:

        I'm curious to know what people think about Anthropic's claim that Claude found 500 high-severity vulnerabilities in open-source packages. Has anyone confirmed that these vulns were indeed high-severity and hadn't been discovered before? Is this development as big a deal as Anthropic says? Any other critiques?

        Thanks for all the responses. So far, projects I understand to have received reports include: Ghostscript, OpenSC, lzw, and CGIF. Are others known? Links to commits that fix the vulns also appreciated.

          Right, but the post doesn't say merely that the reports of the 500 vulns resulted in commits. It says all 500 were high-severity. If true, that would be significant, no?

            @dangoodin to which I said "hang the fuck on" and read a bit more. And hey look, it's in fonts... bounds checking...

              @rootwyrm

              CVSS is 7.8, which is high, no? That would seem to support the Anthropic's claim. What's the significance of the vulns being in fonts . . . bounds checking?

                    @dangoodin the significance is that by their own words, they didn't discover shit. Check the date on that CVE. But they're trying to claim dishonestly that their magical almost-to-AGI stochastic parrot totally discovered it.
                    It did not. Period.

                      I'm not arguing with you. Sorry if it sounds like I am. I don't have the same technical background you do and am asking how the 7.8-severity vuln shouldn't be considered high severity because it involves fonts . . . bounds checking? I'm asking you to explain the reasoning behind your assessment as if I was a student in a security 101 class.
