Title: libbsd: Arbitrary code execution (GLSA 201607-13)
Date: July 20, 2016
A buffer overflow in libbsd might allow remote attackers to execute
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.
Vulnerable: < 0.8.2
Unaffected: >= 0.8.2
Architectures: All supported architectures
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
Remote attackers could potentially execute arbitrary code with the
privileges of the process.
There is no known workaround at this time.
All libbsd users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --verbose --oneshot ">=dev-libs/libbsd-0.8.2"
