Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D

Pavuk contains multiple buffer overflows that can allow a remote
attacker to run arbitrary code.

Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Pavuk is web spider and website mirroring tool.

Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

    -------------------------------------------------------------------
     Package         /  Vulnerable  /                       Unaffected
    -------------------------------------------------------------------
  1  net-misc/pavuk      < 0.9.31                            >=3D 0.9.31

Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Pavuk contains several buffer overflow vulnerabilities in the code
handling digest authentication and HTTP header processing. This issue
is similar to GLSA 200407-19, but contains more vulnerabilities.

Impact
=3D=3D=3D=3D=3D=3D

A remote attacker could cause a buffer overflow, leading to arbitrary
code execution with the rights of the user running Pavuk.

Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

There is no known workaround at this time.

Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

All Pavuk users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=3Dnet-misc/pavuk-0.9.31"
