Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Affected: proot-distro versions before 5.1.5. The install extraction code does not check symlink targets, so a crafted tar archive can plant a symlink that points to a host path and then write files through it. An attacker who gets a user to run proot-distro install on a malicious archive (for example one delivered by a download or CI artifact) can write files on the host at the Termux process's privilege level, such as shell startup files. Upgrade to proot-distro 5.1.5 or later.
