Running tic on the attached file triggers a stack buffer overflow: ,---- | $ tic -I minimized-crash1 | "minimized-crash1", line 1, col 606, terminal '0': Very long string found. Missing separator? | "minimized-crash1", line 1, col 4098, terminal '0': Missing separator | *** buffer overflow detected ***: terminated | [1] 485807 IOT instruction tic -I minimized-crash1 `---- This has been reported upstream yesterday and was promptly addressed in this weekend's patchlevel. I intend to cherry-pick the patch for Bookworm, maybe it could also be included in a Bullseye point release if older versions are affected. The impact seems to be rather low, as the attacker needs to persuade the victim to run tic on crafted input, and thanks to the stack protection nothing worse than a crash should happen.
