Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Heap-based buffer overflow (CVE-ID: CVE-2017-10929)

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

The vulnerability exists due to a boundary error in The grub_memmove function in shlr/grub/kern/misc.c in radare2 1.5.0. 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-2017-9949)

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

The vulnerability exists due to a boundary error within the grub_memmove function in shlr/grub/kern/misc.c when processing a crafted binary file, possibly related to a buffer underflow in fs/ext2.c in GNU GRUB 2.02. 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-2017-9761)

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

The find_eoq function in libr/core/cmd.c in radare2 1.5.0 allows remote attackers to cause a denial of service (heap-based out-of-bounds read and application crash) via a crafted binary file.


4) Use-after-free (CVE-ID: CVE-2017-9762)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when processing a crafted binary file. A remote attackers can cause a denial of service (use-after-free and application crash).

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.


5) Buffer overflow (CVE-ID: CVE-2017-9763)

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

The grub_ext2_read_block function in fs/ext2.c in GNU GRUB before 2013-11-12, as used in shlr/grub/fs/ext2.c in radare2 1.5.0, allows remote attackers to cause a denial of service (excessive stack use and application crash) via a crafted binary file, related to use of a variable-size stack array.


6) Use-after-free (CVE-ID: CVE-2017-9520)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when processing a crafted DEX file. A remote attackers can cause a denial of service (use-after-free and application crash).

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
