Debian DLA-837-1 : radare2 security update

medium Nessus Plugin ID 97395

Language:

Synopsis

The remote Debian host is missing a security update.

Description

CVE-2017-6197 The r_read_* functions in libr/include/r_endian.h in radare2 1.2.1 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted binary file, as demonstrated by the r_read_le32 function.

For Debian 7 'Wheezy', these problems have been fixed in version 0.9-3+deb7u1.

We recommend that you upgrade your radare2 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
