Debian GNU/Linux Advisory: openssl

Oct 01, 2003, 15:52 (0 Talkback[s])

Debian Security Advisory DSA 393-1 Michael Stone
October 1, 2003

Package : openssl
Vulnerability : denial of service
Problem-Type : remote
Debian-specific : no
CVE Ids : CAN-2003-0543 CAN-2003-0544

Dr. Stephen Henson (, using a test suite provided by NISCC (, discovered a number of errors in the OpenSSL ASN1 code. Combined with an error that causes the OpenSSL code to parse client certificates even when it should not, these errors can cause a denial of service (DoS) condition on a system using the OpenSSL code, depending on how that code is used. For example, even though apache-ssl and ssh link to OpenSSL libraries, they should not be affected by this vulnerability. However, other SSL-enabled applications may be vulnerable and an OpenSSL upgrade is recommended.

For the current stable distribution (woody) these problems have been fixed in version 0.9.6c-2.woody.4

For the unstable distribution (sid) these problems have been fixed in version 0.9.7c-1

We recommend that you update your openssl package. Note that you will need to restart services which use the libssl library for this update to take effect.
