patch 9.1.0404: [security] xxd: buffer-overflow with specific flags Commit: https://github.com/vim/vim/commit/67797191e039196128c69ba1538ccaf2a4711323 Author: Lennard Hofmann <lennard.hofmann@web.de> Date: Fri May 10 14:17:26 2024 +0200 patch 9.1.0404: [security] xxd: buffer-overflow with specific flags Problem: [security] xxd: buffer-overflow with specific flags Solution: Correctly calculate the required buffer space (Lennard Hofmann) xxd writes each output line into a global buffer before printing. The maximum size of that buffer was not calculated correctly. This command was crashing in AddressSanitizer: $ xxd -Ralways -g1 -c256 -d -o 9223372036854775808 /etc/passwd This prints a line of 6680 bytes but the buffer only had room for 6549 bytes. If the output from "-b" was colored, the line could be even longer. closes: #14738 Co-authored-by: K.Takata <kentkt@csc.jp> Signed-off-by: Lennard Hofmann <lennard.hofmann@web.de> Signed-off-by: Christian Brabandt <cb@256bit.org>
