problems noted in CAN-2004-0914:
Multiple vulnerabilities in libXpm for 6.8.1 and earlier, as
used in XFree86 and other packages, include (1) multiple integer
overflows, (2) out-of-bounds memory accesses, (3) directory
traversal, (4) shell metacharacter, (5) endless loops, and (6)
memory leaks, which could allow remote attackers to obtain
sensitive information, cause a denial of service (application
crash), or execute arbitary code via a certain XPM image file.
Bump PKGREVISION to 4. Since this is a security-related fix, also
bump the BUILDLINK_RECOMMENDED version for this package.
