In radare2 through 3.5.1, there is a heap-based buffer over-read in the regglangparsechar function of egglang.c. This allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact because of missing length validation in libr/egg/egg.c.

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).

radare2 through 3.5.1 mishandles the RParse API, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact, as demonstrated by newstr buffer overflows during replace operations. This affects libr/asm/asm.c and libr/parse/parse.c.

In radare2 through 3.5.1, cmdmount in libr/core/cmdmount.c has a double free for the ms command.
