Description Agostino Sarubbo gentoo-dev 2014-12-02 08:37:17 UTC 
From ${URL} :

Package: gettext
Version: 0.19.3-1

The attached (slightly corrupted) MO file crashes msgunfmt:

$ msgunfmt messages.mo
Segmentation fault

I suspect there's a integer overflow somewhere.

this is fixed in the 0.19.4 release which is also stable now via bug #551828
Comment 2 Thomas Deutschmann (RETIRED) gentoo-dev 2017-01-21 15:53:37 UTC 
No PoC for ACE/RCE, downgraded to A4.

Repository is clean.
