Title: Patch: Denial of Service (GLSA 201612-12)
Date: December 05, 2016
Patch is vulnerable to a locally generated Denial of Service
Patch takes a patch file containing a difference listing produced by the
diff program and applies those differences to one or more original files,
producing patched versions.
Vulnerable: < 2.7.4
Unaffected: >= 2.7.4
Architectures: All supported architectures
Due to a flaw in Patch, the application can enter an infinite loop when
processing a specially crafted diff file.
A local attacker could pass a specially crafted diff file to Patch,
possibly resulting in a Denial of Service condition.
There is no known workaround at this time.
All patch users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-devel/patch-2.7.4"
