FreeBSD : Courier mail services: remotely exploitable buffer overflows (98bd69c3-834b-11d8-a41f-0020ed76ef5a)

high Nessus Plugin ID 19044

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The Courier set of mail services use a common Unicode library. This library contains buffer overflows in the converters for two popular Japanese character encodings. These overflows may be remotely exploitable, triggered by a maliciously formatted email message that is later processed by one of the Courier mail services. From the release notes for the corrected versions of the Courier set of mail services :

iso2022jp.c: Converters became (upper-)compatible with ISO-2022-JP (RFC1468 / JIS X 0208:1997 Annex 2) and ISO-2022-JP-1 (RFC2237).
Buffer overflow vulnerability (when Unicode character is out of BMP range) has been closed. Convert error handling was implemented.

shiftjis.c: Broken SHIFT_JIS converters has been fixed and became (upper-)compatible with Shifted Encoding Method (JIS X 0208:1997 Annex 1). Buffer overflow vulnerability (when Unicode character is out of BMP range) has been closed. Convert error handling was implemented.

Solution

Update the affected packages.
