Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Texinfo is vulnerable to a buffer overflow that could lead to the |

Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Miloslav Trmac from Red Hat discovered a buffer overflow in the |
| 38 |
"readline()" function of texindex.c. The "readline()" function is |
| 39 |
called by the texi2dvi and texindex commands. |
| 40 |
|
| 41 |
Impact |
| 42 |
====== |
| 43 |
|
| 44 |
By enticing a user to open a specially crafted Texinfo file, an |
| 45 |
attacker could execute arbitrary code with the rights of the user |
| 46 |
running Texinfo. |
| 47 |
|
| 48 |
Workaround |
| 49 |
========== |
| 50 |
|
| 51 |
There is no known workaround at this time. |
| 52 |
|
| 53 |
Resolution |
| 54 |
========== |
| 55 |
|
| 56 |
All Texinfo users should upgrade to the latest version: |
| 57 |
|
| 58 |
# emerge --sync |
| 59 |
# emerge --ask --oneshot --verbose ">=sys-apps/texinfo-4.8-r5" |
| 60 |
