Summary

CVE-2016-9591
Use-after-free on heap in jas_matrix_destroy
The vulnerability exists in code responsible for re-encoding the
decoded input image file to a JP2 image. The vulnerability is
caused by not setting related pointers to be null after the
pointers are freed (i.e. missing Setting-Pointer-Null operations
after free). The vulnerability can further cause double-free.

CVE-2016-10251
Integer overflow in the jpc_pi_nextcprl function in jpc_t2cod.c in
JasPer before 1.900.20 allows remote attackers to have unspecified
impact via a crafted file, which triggers use of an uninitialized
value.
