When zgrep is applied on the attacker's chosen file name (for example, a crafted file name), this can overwrite an attacker's content to an arbitrary attacker-selected file. This flaw occurs due to insufficient validation when processing filenames with two or more newlines where selected content and the target file names are embedded in crafted multi-line file names. This flaw allows a remote, low privileged attacker to force zgrep to write arbitrary files on the system.\n\n## Affected\n\n- `gzip < 1.12`\n- `jboss_data_grid = 7.0.0`\n- `debian_linux = 10.0`\n- `xz < 5.2.5`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `gzip 1.12`\n- `xz 5.2.5`","depth":"twilight","depthScore":49,"depthScoreParts":{"impact":48.4,"likelihood":1,"exploitation":0,"ransomware":0},"changes":[]}
