Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D
A buffer overflow vulnerability in ed may allow for the remote
execution of arbitrary code.
Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
GNU ed is a basic line editor. red is a restricted version of ed that
does not allow shell command execution.

Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Alfredo Ortega from Core Security Technologies reported a heap-based
buffer overflow in the strip_escapes() function when processing overly
long filenames.
Impact
=3D=3D=3D=3D=3D=3D
A remote attacker could entice a user to process specially crafted
commands with ed or red, possibly resulting in the execution of
arbitrary code with the privileges of the user running the application.
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 GNU ed users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=3Dsys-apps/ed-1.0"
