1. Gentoo Linux Security Advisory

Package	Vulnerable versions	Unaffected versions	Architecture(s)
mail-filter/spamdyke	< 4.3.0	>= 4.3.0	All supported architectures

Related bugreports: #399157

A buffer overflow in spamdyke might allow remote attackers to execute arbitrary code.

2. Impact Information

spamdyke is a drop-in connection-time spam filter for qmail.

Boundary errors related to the "snprintf()" and "vsnprintf()" functions in spamdyke could cause a buffer overflow.

A remote attacker could possibly execute arbitrary code or cause a Denial of Service.

3. Resolution Information

There is no known workaround at this time.

All spamdyke users should upgrade to the latest version:

Code Listing 3.1: Resolution

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=mail-filter/spamdyke-4.3.0"
