Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Two vulnerabilities have been discovered in HT Editor, potentially |
| 19 |
leading to the execution of arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
HT is a hex editor, designed to help analyse and modify executable |
| 25 |
files. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |

| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 app-editors/hteditor < 0.8.0-r2 >= 0.8.0-r2 |

|
| 35 |
Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Tavis Ormandy of the Gentoo Linux Security Team discovered an integer |
| 39 |
overflow in the ELF parser, leading to a heap-based buffer overflow. |
| 40 |
The vendor has reported that an unrelated buffer overflow has been |
| 41 |
discovered in the PE parser. |
| 42 |
|
| 43 |
Impact |
| 44 |
====== |
| 45 |
|
| 46 |
Successful exploitation would require the victim to open a specially |
| 47 |
crafted file using HT, potentially permitting an attacker to execute |
| 48 |
arbitrary code. |
| 49 |
|
| 50 |
Workaround |
| 51 |
========== |
| 52 |
|
| 53 |
There is no known workaround at this time. |
| 54 |
|
| 55 |
Resolution |
| 56 |
========== |
| 57 |
|
| 58 |
All hteditor users should upgrade to the latest version: |
| 59 |
|
| 60 |
# emerge --sync |
| 61 |
# emerge --ask --oneshot --verbose ">=app-editors/hteditor-0.8.0-r2" |
| 62 |
