Description Agostino Sarubbo gentoo-dev 2017-07-19 13:21:45 UTC
From ${URL} :

The cabd_read_string function in mspack/cabd.c in libmspack 0.5alpha,
as used in ClamAV 0.99.2 and other products, allows remote attackers to
cause a denial of service (stack-based buffer over-read and application
crash) via a crafted CAB file.


Upstream bug:

@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
