Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple buffer overflow vulnerabilities have been discovered in Git. |
| 19 |
|
| 20 |
Background |
| 21 |
========== |
| 22 |
|
| 23 |
Git is a distributed version control system. |
| 24 |
|
| 25 |
Affected packages |
| 26 |
================= |
| 27 |
|
| 28 |
------------------------------------------------------------------- |
| 29 |
Package / Vulnerable / Unaffected |
| 30 |
------------------------------------------------------------------- |
| 31 |
1 dev-util/git < 1.5.6.4 >= 1.5.6.4 |
| 32 |
|
| 33 |
Description |
| 34 |
=========== |
| 35 |
|
| 36 |
Multiple boundary errors in the functions diff_addremove() and |
| 37 |
diff_change() when processing overly long repository path names were |
| 38 |
reported. |
| 39 |
|
| 40 |
Impact |
| 41 |
====== |
| 42 |
|
| 43 |
A remote attacker could entice a user to run commands like "git-diff" |
| 44 |
or "git-grep" on a specially crafted repository, possibly resulting in |
| 45 |
the remote execution of arbitrary code with the privileges of the user |
| 46 |
running the application. |
| 47 |
|
| 48 |
Workaround |
| 49 |
========== |
| 50 |
|
| 51 |
There is no known workaround at this time. |
| 52 |
|
| 53 |
Resolution |
| 54 |
========== |
| 55 |
|
| 56 |
All Git users should upgrade to the latest version: |
| 57 |
|
| 58 |
# emerge --sync |
| 59 |
# emerge --ask --oneshot --verbose ">=dev-util/git-1.5.6.4" |
| 60 |
