PACKAGE :dietlibc |

SUMMARY :integer overflow |

There is an integer overflow present in the xdr_array() function |
| 15 |
distributed as part of the Sun Microsystems XDR library. This overflow |
| 16 |
has been shown to lead to remotely exploitable buffer overflows in |
| 17 |
multiple applications, leading to the execution of arbitrary code. |
| 18 |
Although the library was originally distributed by Sun Microsystems, |
| 19 |
multiple vendors have included the vulnerable code in their own |
| 20 |
implementations. |
| 21 |
|
| 22 |
DETAIL |
| 23 |
|
| 24 |
The XDR (external data representation) libraries are used to provide |
| 25 |
platform-independent methods for sending data from one system process to |
| 26 |
another, typically over a network connection. Such routines are commonly |
| 27 |
used in remote procedure call (RPC) implementations to provide transparency |
| 28 |
to application programmers who need to use common interfaces to interact |
| 29 |
with many different types of systems. The xdr_array() function in the XDR |
| 30 |
library provided by Sun Microsystems contains an integer overflow that can |
| 31 |
lead to improperly sized dynamic memory allocation. Subsequent problems like |
| 32 |
buffer overflows may result, depending on how and where the vulnerable |
| 33 |
xdr_array() function is used. |

SOLUTION |
| 41 |
|
| 42 |
It is recommended that all Gentoo Linux users who are running |
| 43 |
dev-libs/dietlibc-0.16 and earlier update their systems |
| 44 |
as follows: |
| 45 |
|
| 46 |
emerge rsync |
| 47 |
emerge dietlibc |
| 48 |
emerge clean |
| 49 |
