Gentoo Linux Security Advisory

Title: libbsd: Arbitrary code execution (GLSA 201607-13)
Severity: normal
Exploitable: remote
Date: July 20, 2016
Bug(s): #573160
ID: 201607-13

Synopsis

A buffer overflow in libbsd might allow remote attackers to execute
arbitrary code.


Background

This library provides useful functions commonly found on BSD systems,
and lacking on others like GNU systems, thus making it easier to port
projects with strong BSD origins, without needing to embed the same code
over and over again on each project.


Affected Packages

Package: dev-libs/libbsd
Vulnerable: < 0.8.2
Unaffected: >= 0.8.2
Architectures: All supported architectures


Description

libbsd contains a buffer overflow in the fgetwln() function. An if
statement, which is responsible for checking the necessity to reallocate
memory in the target buffer, is off by one therefore an out of bounds
write occurs.


Impact

Remote attackers could potentially execute arbitrary code with the
privileges of the process.


Workaround

There is no known workaround at this time.

Resolution

All libbsd users should upgrade to the latest version:
Code:
# emerge --sync
      # emerge --ask --verbose --oneshot ">=dev-libs/libbsd-0.8.2"
