Alpine: multiple cargo packages, multiple rust packages, multiple wasm-component-ld packages: security update to 1.78.0-r1
medium Tenable Self-Hosted Container Security Plugin ID 439147
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- tar-rs is a tar archive reading/writing library for Rust. In versions 0.4.44 and below, 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. (CVE-2026-33056)
Solution
Update the cargo library and its related packages to version 1.78.0-r1 or later.See Also
