[X2Go-Dev] Bug#777: nx-libs: incorrect usage of scanf

package: nx-libs version: head

In different parts of the nx-libs library you can find usages of scanf like

/* check for MESA_GAMMA environment variable */ gamma = _mesa_getenv("MESA_GAMMA"); if (gamma) { v->RedGamma = v->GreenGamma = v->BlueGamma = 0.0; sscanf( gamma, "%f %f %f", &v->RedGamma, &v->GreenGamma, &v->BlueGamma );

According to cppcheck:

scanf without field width limits can crash with huge input data on libc versions older than 2.13-25. Add a field width specifier to fix this problem: %i => %3i
