Title: CVE-2020-37121 - buffer overflow exploit
Post by: SharkCZ on February 12, 2026, 02:51:51 pm

Seems https://nvd.nist.gov/vuln/detail/CVE-2020-37121 about a buffer overflow related exploit got published last week, but I can't find any additional information. Does anybody know what it is about? I can't see a connection between a crafted M3U playlist and C::B.

Probably all programs compiled with SEH ten years ago are affected, but good luck opening a M3U with C::B  8).

From the NVD description it looks like a generic SEH-based buffer overflow pattern rather than something specific to Code::Blocks itself. Has anyone checked whether this CVE is tied to a bundled third-party library rather than the IDE core?
