JBIG-KIT is a software implementation of the JBIG1 data compression standard.
JBIG-KIT contains a stack-based buffer overflow in the jbg_dec_in function in libjbig/jbig.c.
A remote attacker could possibly cause a Denial of Service condition via a specially crafted image file.
There is no known workaround at this time.
All JBIG-KIT users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/jbigkit-2.1"
