UUdeview is encoder and decoder supporting various binary formats. NZBGet is a command-line based binary newsgrabber supporting .nzb files.
UUdeview makes insecure usage of the tempnam() function when creating temporary files. NZBGet includes a copy of the vulnerable code.
A local attacker could exploit this vulnerability to overwrite arbitrary files on the system.
There is no known workaround at this time.
All UUDview users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/uudeview-0.5.20-r1"
All NZBget users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=news-nntp/nzbget-0.4.0"
