Description

less through 653 allows OS command execution via a newline character in the name of a file, because quoting is mishandled in filename.c. Exploitation typically requires use with attacker-controlled file names, such as the files extracted from an untrusted archive. Exploitation also requires the LESSOPEN environment variable, but this is set by default in many common cases.

Affected products

• Debian Linux: 10.0
• Greenwoodsoftware Less: through 653
• NetApp Bootstrap Os: all versions
• NetApp Hci Storage Nodes: all versions
• NetApp Solidfire: all versions
