Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple vulnerabilities have been found in cURL, the worst of which |
| 19 |
might allow remote execution of arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
cURL is a command line tool for transferring files with URL syntax, |
| 25 |
supporting numerous protocols. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |

|

------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |

Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Multiple vulnerabilities have been found in cURL: |
| 39 |
|
| 40 |
* When zlib is enabled, the amount of data sent to an application for |
| 41 |
automatic decompression is not restricted (CVE-2010-0734). |
| 42 |
* When performing GSSAPI authentication, credential delegation is |
| 43 |
always used (CVE-2011-2192). |
| 44 |
* When SSL is enabled, cURL improperly disables the OpenSSL workaround |
| 45 |
to mitigate an information disclosure vulnerability in the SSL and |
| 46 |
TLS protocols (CVE-2011-3389). |
| 47 |
* libcurl does not properly verify file paths for escape control |
| 48 |
characters in IMAP, POP3 or SMTP URLs (CVE-2012-0036). |
| 49 |
|
| 50 |
Impact |
| 51 |
====== |
| 52 |
|
| 53 |
A remote attacker could entice a user or automated process to open a |
| 54 |
specially crafted file or URL using cURL, possibly resulting in the |
| 55 |
remote execution of arbitrary code, a Denial of Service condition, |
| 56 |
disclosure of sensitive information, or unwanted actions performed via |
| 57 |
the IMAP, POP3 or SMTP protocols. Furthermore, remote servers may be |
| 58 |
able to impersonate clients via GSSAPI requests. |
| 59 |
|
| 60 |
Workaround |
| 61 |
========== |
| 62 |
|
| 63 |
There is no known workaround at this time. |
| 64 |
|
| 65 |
Resolution |
| 66 |
========== |
| 67 |
|
| 68 |
All cURL users should upgrade to the latest version: |
| 69 |
|
| 70 |
# emerge --sync |
| 71 |
# emerge --ask --oneshot --verbose ">=net-misc/curl-7.24.0" |
| 72 |
|
