Synopsis
A malicious tar archive could trigger a Buffer overflow in GNU tar, potentially resulting in the execution of arbitrary code.Background
GNU tar is the standard GNU utility for creating and manipulating tar archives, a common format used for creating backups and distributing files on UNIX-like systems.
Affected packages
Package | Vulnerable | Unaffected | Architecture(s) |
---|---|---|---|
app-arch/tar | < 1.15.1-r1 | >= 1.15.1-r1 | All supported architectures |
Description
Jim Meyering discovered a flaw in the handling of certain header fields that could result in a buffer overflow when extracting or listing the contents of an archive.
Impact
A remote attacker could construct a malicious tar archive that could potentially execute arbitrary code with the privileges of the user running GNU tar.
Workaround
There is no known workaround at this time.
Resolution
All GNU tar users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-arch/tar-1.15.1-r1"
