Details

In radare2 through 3.5.1, the rcccontext function of libr/egg/egglang.c mishandles changing context. This allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact (invalid memory access in regglangparsechar; invalid free in rccpusharg).
