CVE-2010-0562
CVSS v2.0
6.8
Medium
| Vector | AV:N/AC:M/Au:N/C:P/I:P/A:P |
Name of the Vulnerable Software and Affected Versions
fetchmail versions 6.3.11 through 6.3.13
Description
The issue allows remote attackers to cause a denial of service or possibly execute arbitrary code via an SSL X.509 certificate containing non-printable characters with the high bit set. This triggers a heap-based buffer overflow during escaping in the
sdump function when running in verbose mode on platforms for which char is signed.Recommendations
For fetchmail versions 6.3.11 through 6.3.13, consider disabling the verbose mode as a temporary workaround until a patch is available. Restrict access to SSL X.509 certificates to minimize the risk of exploitation.
Fix
Buffer Overflow
