Mandriva Linux Security Advisory : fetchmail (MDVSA-2010:037)
Medium Nessus Plugin ID 48173
SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionA vulnerability have been discovered and corrected in fetchmail :
The sdump function in sdump.c in fetchmail 6.3.11, 6.3.12, and 6.3.13, when running in verbose mode on platforms for which char is signed, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via an SSL X.509 certificate containing non-printable characters with the high bit set, which triggers a heap-based buffer overflow during escaping (CVE-2010-0562).
This update provides fetchmail 6.3.14, which is not vulnerable to this issue.
SolutionUpdate the affected fetchmail, fetchmail-daemon and / or fetchmailconf packages.
