Problem type : local (remote)
Debian-specific: no
CVE ID : CVE-2006-3251
BugTraq ID : 18659

Andreas Seltenreich discovered a buffer overflow in hashcash, a
postage payment scheme for email that is based on hash calculations,
which could allow attackers to execute arbitrary code via specially
crafted entries.

For the stable distribution (sarge) this problem has been fixed in
version 1.17-1sarge1.

version 1.21-1.

We recommend that you upgrade your hashcash package.
