Title: Dropbear: Multiple vulnerabilities (GLSA 201309-20)
Date: September 26, 2013
Bug(s): #328409, #405607
Multiple vulnerabilities have been found in Dropbear, the worst of
which could lead to arbitrary code execution.
Dropbear is an SSH server and client designed with a small memory
Vulnerable: < 2012.55
Unaffected: >= 2012.55
Architectures: All supported architectures
Multiple vulnerabilities have been discovered in Dropbear. Please review
the CVE identifier and Gentoo bug referenced below for details.
A remote attacker could send a specially crafted request to trigger a
use-after-free condition, possibly resulting in arbitrary code execution
or a Denial of Service condition. Additionally, the bundled version of
libtommath has an error in its prime number generation, which could
result in the generation of weak keys.
There is no known workaround at this time.
All Dropbear users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/dropbear-2012.55"
