RUSTSEC-2026-0067
No affected components available
In versions 0.4.44 and below of tar-rs, when unpacking a tar archive, the tar
crate's unpack_dir function uses fs::metadata() to check
whether a path that already exists is a directory. Because fs::metadata()
follows symbolic links, a crafted tarball containing a symlink entry followed
by a directory entry with the same name causes the crate to treat the symlink
target as a valid existing directory — and subsequently apply chmod to it. This
allows an attacker to modify the permissions of arbitrary directories outside
the extraction root.
This issue has been fixed in version 0.4.45.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights.
Limited exploitation activity has been observed. Close monitoring and planned remediation are recommended.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
