Package : libnet-server-perl
Vulnerability : format string
Problem type : remote
Debian-specific: no
CVE ID : CVE-2005-1127
Debian Bug : 378640
Peter Bieringer discovered that the "log" function in the Net::Server
Perl module, an extensible, general perl server engine, is not safe
against format string exploits.
The old stable distribution (woody) does not contain this package.
For the stable distribution (sarge) this problem has been fixed in
version 0.87-3sarge1.
