Description

This security bulletin contains information about 3 secuirty vulnerabilities.


1) Double Free (CVE-ID: CVE-2019-12865)

The vulnerability allows a remote user to perform a denial of service (DoS) attacl.

The vulnerability exists due to a boundary error in the cmd_mount() function in libr/core/cmd_mount.c when processing "ms" command. A remote authenticated user can pass specially crafted data to the application, trigger double free error and crash the service.


2) Out-of-bounds read (CVE-ID: CVE-2019-12790)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error in In radare2 through 3.5.1, there is a heap-based buffer over-read in the r_egg_lang_parsechar function of egg_lang.c. This. A remote attacker can perform a denial of service (application crash) or possibly have unspecified other impact because of missing length validation in libr/egg/egg.c.


3) Buffer overflow (CVE-ID: CVE-2019-12802)

The vulnerability allows a local non-authenticated attacker to execute arbitrary code.

In radare2 through 3.5.1, the rcc_context function of libr/egg/egg_lang.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 r_egg_lang_parsechar; invalid free in rcc_pusharg).
