17 old software bugs that took way too long to squash
Summary
This article discusses 17 old software bugs that took over a decade to discover and fix, including a 30-year-old flaw in the libpng graphics library (a widely used image processing tool) discovered in 2026. The article notes that AI tools like Claude are now able to scan code and test for vulnerabilities much faster than humans could manually, which is accelerating the discovery of these long-dormant security flaws rather than creating entirely new types of exploits.
Solution / Mitigation
For the libpng vulnerability (CVE-2026-25646), the source states that 'many Linux distributions (Debian, Red Hat, Ubuntu), desktop apps, and some Java runtimes rely on vulnerable versions of the library and need to be patched,' but does not specify what the patch or update is. For PrintDemon, the source notes that 'Microsoft's fixes over the years had been patches rather than a complete rebuild of the printing subsystem' but does not explicitly state what fix was applied. N/A -- no specific mitigation details discussed in source.
