[GLSA-200406-22] Pavuk: Remote buffer overflow Vulnerability Scan

Vulnerability Scan Summary
Pavuk: Remote buffer overflow

Detailed Explanation for this Vulnerability Test
The remote host is affected by the vulnerability described in GLSA-200406-22
(Pavuk: Remote buffer overflow)

When Pavuk connects to a web server and the server sends back the HTTP
status code 305 (Use Proxy), Pavuk copies data from the HTTP Location
header in an unsafe manner. This bug was discovered by Ulf Harnhammar
of the Debian Security Audit Project.


A possible hacker could cause a stack-based buffer overflow which could lead to
arbitrary code execution with the rights of the user running Pavuk.


There is no known workaround at this time. All users are encouraged to
upgrade to the latest available version.

All Pavuk users should upgrade to the latest stable version:
# emerge sync
# emerge -pv ">=net-misc/pavuk-0.9.28-r2"
# emerge ">="net-misc/pavuk-0.9.28-r2

Threat Level: High
