GLSA-200710-09 : NX 2.1: User-assisted execution of arbitrary code

High Nessus Plugin ID 26980


The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-200710-09 (NX 2.1: User-assisted execution of arbitrary code)

Chris Evans reported an integer overflow within the FreeType PCF font file parser (CVE-2006-1861). NX and NX Node are vulnerable to this due to shipping XFree86 4.3.0, which includes the vulnerable FreeType code.
Impact :

A remote attacker could exploit these integer overflows by enticing a user to load a specially crafted PCF font file which might lead to the execution of arbitrary code with the privileges of the user on the machine running the NX server.
Workaround :

There is no known workaround at this time.


All NX users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-misc/nx-3.0.0' All NX Node users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-misc/nxnode-3.0.0-r3'
