Gentoo has issued an update for ncompress. This fixes an old vulnerability, which potentially can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to boundary errors within the handling of command line options in "compress" and "uncompress". This can be exploited to cause a buffer overflow by supplying e.g. a specially crafted, overly long filename.
Successful exploitation can lead to execution of arbitrary code in context of the process using the ncompress utility.
Solution: Update to "app-arch/ncompress-4.2.4-r1" or later.
