Debian Security Advisory DSA-4004-1 security@debian.org
https://www.debian.org/security/ Sebastien Delafond
October 20, 2017 https://www.debian.org/security/faq
- - -------------------------------------------------------------------------
Package : jackson-databind
CVE ID : CVE-2017-7525
Debian Bug : 870848
Liao Xinxi discovered that jackson-databind, a Java library used to
parse JSON and other data formats, did not properly validate user
input before attemtping deserialization. This allowed an attacker to
perform code execution by providing maliciously crafted input.
For the oldstable distribution (jessie), this problem has been fixed
in version 2.4.2-2+deb8u1.
For the stable distribution (stretch), this problem has been fixed in
version 2.8.6-1+deb9u1.
We recommend that you upgrade your jackson-databind packages.
