Package : unzip
Version : 6.0-16+deb8u4
CVE ID : CVE-2019-13232
Debian Bug : 931433
David Fifield discovered a way to construct non-recursive "zip bombs"
that achieve a high compression ratio by overlapping files inside the
zip container. However the output size increases quadratically in the
input size, reaching a compression ratio of over 28 million
(10 MB -> 281 TB) at the limits of the zip format which can cause a
denial-of-service. Mark Adler provided a patch to detect and reject
such zip files for the unzip program.
For Debian 8 "Jessie", this problem has been fixed in version
6.0-16+deb8u4.
We recommend that you upgrade your unzip packages.
