Public bug reported: Applications using libedit to process user input segfault on Ubuntu 19.04 when they are passed a long input string. The issue can easily be reproduced with the example programs bundled with the library.
The issue has been fixed in upstream NetBSD by this diff https://github.com/IIJ-NetBSD/netbsd- src/commit/2a926170e92dc4ab635b3c94c1e1bbbcc7f9494c , however the latest Linux port release (libedit-20181209-3.1.tar.gz) does not contain this fix. Applying it manually does indeed correct the issue, and the affected applications no longer crash. I have contacted the Linux port maintainer and I am awaiting for a response, however I would like to see this fixed in disco. Cosmic and older are not affected. I have attached a log demonstrating a crash, compiled with AddressSanitizer. ** Affects: libedit (Ubuntu) Importance: Undecided Status: New ** Attachment added: "libedit_asan.txt" https://bugs.launchpad.net/bugs/1821528/+attachment/5249080/+files/libedit_asan.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1821528 Title: libedit applications segfault when passed long strings To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libedit/+bug/1821528/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
