Description
===========

- CVE-2018-11375 (denial of service)

The _inst__lds() function in radare2 2.5.0 allows remote attackers to
cause a denial of service (heap-based out-of-bounds read and
application crash) via a crafted binary file.

- CVE-2018-11376 (denial of service)

The r_read_le32() function in radare2 2.5.0 allows remote attackers to
cause a denial of service (heap-based out-of-bounds read and
application crash) via a crafted ELF file.

- CVE-2018-11377 (denial of service)

The avr_op_analyze() function in radare2 2.5.0 allows remote attackers
to cause a denial of service (heap-based out-of-bounds read and
application crash) via a crafted binary file.

- CVE-2018-11378 (arbitrary code execution)

The wasm_dis() function in libr/asm/arch/wasm/wasm.c has a stack-buffer
overflow that may result in denial-of-service or possibly have
unspecified other impact via a crafted WASM file.

- CVE-2018-11379 (denial of service)

The get_debug_info() function in radare2 2.5.0 allows remote attackers
to cause a denial of service (heap-based out-of-bounds read and
application crash) via a crafted PE file.

- CVE-2018-11380 (denial of service)

The parse_import_ptr() function in radare2 2.5.0 allows remote
attackers to cause a denial of service (heap-based out-of-bounds read
and application crash) via a crafted Mach-O file.

- CVE-2018-11381 (denial of service)

The string_scan_range() function in radare2 2.5.0 allows remote
attackers to cause a denial of service (heap-based out-of-bounds read
and application crash) via a crafted binary file.

- CVE-2018-11382 (denial of service)

The _inst__sts() function in radare2 2.5.0 allows remote attackers to
cause a denial of service (heap-based out-of-bounds read and
application crash) via a crafted binary file.

- CVE-2018-11383 (denial of service)

The r_strbuf_fini() function in radare2 2.5.0 allows remote attackers
to cause a denial of service (invalid free and application crash) via a
crafted ELF file because of an uninitialized variable in the CPSE
handler in libr/anal/p/anal_avr.c.

- CVE-2018-11384 (denial of service)

The sh_op() function in radare2 2.5.0 allows remote attackers to cause
a denial of service (heap-based out-of-bounds read and application
crash) via a crafted ELF file.

Impact
======

A remote attacker is able to execute arbitrary code or crash the
application via a specially crafted file.
