Package        : rsync
Vulnerability  : buffer overflow
Problem type   : remote
Debian-specific: no
CVE Id(s)      : CVE-2007-4091

Sebastian Krahmer discovered that rsync, a fast remote file copy program,
contains an off-by-one error which might allow remote attackers to execute
arbitary code via long directory names.

For the stable distribution (etch), this problem has been fixed in version
2.6.9-2etch1.

For the old stable distribution (sarge), this problem is not presnt.

For the unstable distribution (sid) this problem will be fixed soon.

We recommend that you upgrade your rsync package.
