Date of Resolved Release: 17-Sep-2008
SA Document Body
Manipulated Tag Files used with Solaris Text Editors May Lead to
Execution of Arbitrary Code
1. Impact
A security vulnerability in the Solaris text editors (vi(1), ex(1),
vedit(1), view(1), edit(1)), related to the handling of tags (see
ctags(1)) may allow a local unprivileged user to execute arbitrary
code with the privileges of another user.
Sun acknowledges with thanks, "Eli the Bearded" for bringing this
issue to our attention.
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform:
* Solaris 8 without patch 110903-08
* Solaris 9 without patch 113031-04
* Solaris 10 without patch 120830-06
x86 Platform:
* Solaris 8 without patch 110904-08
* Solaris 9 without patch 116479-02
* Solaris 10 without patch 120831-06
3. Symptoms
There are no reliable symptoms that would indicate the described issue
has occurred.
4. Workaround
To avoid this issue, do not use the '-t' option or the ':tag' command
with the Solaris text editors (vi, ex, vedit, view or edit). Use the
ctags(1) utility to recreate the tags file.
5. Resolution
This issue is addressed in the following releases:
SPARC Platform
* Solaris 8 with patch 110903-08 or later
* Solaris 9 with patch 113031-04 or later
* Solaris 10 with patch 120830-06 or later
x86 Platform
