Package : zsync
Vulnerability : DOS
Problem-Type : buffer overflow
Debian-specific: no
CVE ID : CAN-2005-1849, CAN-2005-2096
zsync, a file transfer program, includes a modified local copy of
the zlib library, and is vulnerable to certain bugs fixed previously
in the zlib package.
The old stable distribution (woody) does not contain the zsync
package.
For the stable distribution (sarge) this problem has been fixed in
version 0.3.3-1.sarge.1.

version 0.4.0-2.
We recommend that you upgrade your zsync package.
