Description

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

Multiple off-by-one errors in the (1) jpc_dec_cp_setfromcox and (2) jpc_dec_cp_setfromrgn functions in jpc/jpc_dec.c in JasPer 1.900.1 and earlier allow remote attackers to execute arbitrary code via a crafted jp2 file, which triggers a heap-based buffer overflow.
