Description Andrej Nemec 2019-01-07 13:44:35 UTC

CVE-2018-20455

In radare2 prior to 3.1.1, the parseOperand function inside libr/asm/p/asm_x86_nz.c may allow attackers to cause a denial of service (application crash via a stack-based buffer overflow) by crafting an input file, a related issue to CVE-2018-20456.

CVE-2018-20456

In radare2 prior to 3.1.1, the parseOperand function inside libr/asm/p/asm_x86_nz.c may allow attackers to cause a denial of service (application crash in libr/util/strbuf.c via a stack-based buffer over-read) by crafting an input file, a related issue to CVE-2018-20455.

CVE-2018-20457

In radare2 through 3.1.3, the assemble function inside libr/asm/p/asm_arm_cs.c allows attackers to cause a denial-of-service (application crash via an r_num_calc out-of-bounds read) by crafting an arm assembly input because a loop uses an incorrect index in armass.c and certain length validation is missing in armass64.c, a related issue to CVE-2018-20459.

CVE-2018-20458

In radare2 prior to 3.1.1, r_bin_dyldcache_extract in libr/bin/format/mach0/dyldcache.c may allow attackers to cause a denial-of-service (application crash caused by out-of-bounds read) by crafting an input file.

CVE-2018-20459

In radare2 through 3.1.3, the armass_assemble function in libr/asm/arch/arm/armass.c allows attackers to cause a denial-of-service (application crash by out-of-bounds read) by crafting an arm assembly input because a loop uses an incorrect index in armass.c and certain length validation is missing in armass64.c, a related issue to CVE-2018-20457.

CVE-2018-20460

In radare2 prior to 3.1.2, the parseOperands function in libr/asm/arch/arm/armass64.c allows attackers to cause a denial-of-service (application crash caused by stack-based buffer overflow) by crafting an input file.

https://github.com/radare/radare2/issues/12376

CVE-2018-20461

In radare2 prior to 3.1.1, core_anal_bytes in libr/core/cmd_anal.c allows attackers to cause a denial-of-service (application crash caused by out-of-bounds read) by crafting a binary file.
