Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Heap-based buffer overflow (CVE-ID: CVE-2017-6194)

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.

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


2) Stack-based buffer overflow (CVE-ID: CVE-2017-6448)

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.


3) Buffer overflow (CVE-ID: CVE-2017-6319)

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

The dex_parse_debug_item function in libr/bin/p/bin_dex.c in radare2 1.2.1 allows remote attackers to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other impact via a crafted DEX file.


4) Out-of-bounds read (CVE-ID: CVE-2017-6387)

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

The dex_loadcode function in libr/bin/p/bin_dex.c in radare2 1.2.1 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted DEX file.


5) NULL pointer dereference (CVE-ID: CVE-2017-6415)

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

The vulnerability exists due to a NULL pointer dereference error. A remote attacker can trigger denial of service conditions via a crafted DEX file.


6) NULL pointer dereference (CVE-ID: CVE-2017-6197)

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

The vulnerability exists due to a NULL pointer dereference error. A remote attacker can trigger denial of service conditions via a crafted binary file, as demonstrated by the r_read_le32 function.
