|Gentoo Linux Security Advisory
Title: Tar: Denial of Service (GLSA 201903-05)
A vulnerability in Tar could led to a Denial of Service condition.
The Tar program provides the ability to create and manipulate tar
Vulnerable: < 1.30-r1
Unaffected: >= 1.30-r1
Architectures: All supported architectures
The sparse_dump_region function in sparse.c file in Tar allows an
infinite loop using the --sparse option.
A local attacker could cause a Denial of Service condition by modifying
a file that is supposed to be archived by a different user’s process
(e.g., a system backup running as root).
There is no known workaround at this time.
All Tar users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=app-arch/tar-1.30-r1"
