zip buffer overflow detected with umlaut o (ö) in the filename

[John Allsup]

# Umlaut o in filename causes buffer overflow error.
# This is in 24.04. Problem does not occur with binary from
# 22.04 run on same 24.04 system.
# Tested on two separate installs of 24.04 (One Thinkpad T470s, one Thinkpad T450)
# I have tried apt-get install --reinstall

# Example
$ touch ö
$ zip -9r o.zip ö
*** buffer overflow detected ***: terminated

This bug report was generated on a Thinkpad T470s that was initially installed with 23.10 and then upgraded to 24.04. The same bug occurs on a Thinkpad T450 that was a clean install from a 24.04 ISO.

If I get the source via apt-get source, and build locally using make unix/Makefile generic_gcc, this bug does not occur.

Status changed to 'Confirmed' because the bug affects multiple users.
