Description
Directory traversal vulnerability in ZZIPlib 0.13.69 allows attackers to overwrite arbitrary files via a .. (dot dot) in a zip file, because of the function unzzip_cat in the bins/unzzipcat-mem.c file.
It was discovered that zziplib is vulnerable to a directory traversal flaw in most of its unzip binaries, including unzip-mem, unzzipcat-mem, unzzipcat-big, unzzipcat-mix, and unzzipcat-zip. An attacker may use this flaw to write files outside the intended target directory, overwriting existing files, or creating new ones.
