Doc Text: |
A flaw was found in fetchmail. The flaw lies in how fetchmail when running in verbose mode using the -v flag tries to log long messages that are created from long headers. An attacker could potentially use this flaw to cause a Denial of Service attack or crash. The highest threat from this vulnerability is to data availability. This flaw was earlier identified by CVE-2008-2711 and fixed, however it recently got reintroduced due to a code refactoring issue. The current bug fix applies a different approach than the earlier one.
