Package : spamassassin Vulnerability : mail header parsing error Problem type : remote DOS Debian-specific: no CVE Id(s) : CAN-2005-1266 Debian Bug : 314447
A vulnerability was recently found in the way that SpamAssassin parses certain email headers. This vulnerability could cause SpamAssassin to consume a large number of CPU cycles when processing messages containing these headers, leading to a potential denial of service (DOS) attack.
The version of SpamAssassin in the old stable distribution (woody) is not vulnerable.
For the stable distribution (sarge), this problem has been fixed in version 3.0.3-2. Note that packages are not yet ready for certain architectures; these will be released as they become available.
For the unstable distribution (sid), this problem has been fixed in version 3.0.4-1.
We recommend that you upgrade your sarge or sid spamassassin package.
