Package : ndiswrapper
Vulnerability : buffer overflow
Problem type : remote
Debian-specific: no
CVE Id : CVE-2008-4395
Debian Bugs : 504696


Anders Kaseorg discovered that ndiswrapper suffers from buffer overflows
via specially crafted wireless network traffic, due to incorrectly
handling long ESSIDs. This could lead to the execution of arbitrary
code.


For the oldstable distribution (etch), this problem has been fixed in
version 1.28-1+etch1.

For the stable distribution (lenny), this problem has been fixed in
version 1.53-2, which was already included in the lenny release.

For the testing distribution (squeeze) and the unstable distribution
(sid), this problem has been fixed in version 1.53-2.
