Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Heap-based buffer overflow

EUVDB-ID: #VU39296

Risk: Medium

CVSSv4.0: 5.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2017-6194

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in The relocs function in libr/bin/p/bin_bflt.c in radare2 1.2.1. A remote attacker can use a crafted binary file. to trigger heap-based buffer overflow and execute arbitrary code on the target system.

2) Stack-based buffer overflow

EUVDB-ID: #VU39297

Risk: Medium

CVSSv4.0: 5.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2017-6448

CWE-ID: CWE-121 - Stack-based buffer overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the dalvik_disassemble function in libr/asm/p/asm_dalvik.c when processing a crafted DEX file. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation
