Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Heap-based buffer overflow (CVE-ID: CVE-2017-12141)

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

The vulnerability exists due to a boundary error in In ytnef 1.9.2, a heap-based buffer overflow vulnerability was found in the function TNEFFillMapi in ytnef.c, which. A remote attacker can use a crafted 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) Out-of-bounds read (CVE-ID: CVE-2017-12142)

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

In ytnef 1.9.2, an invalid memory read vulnerability was found in the function SwapDWord in ytnef.c, which allows attackers to cause a denial of service via a crafted file.


3) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2017-12144)

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

In ytnef 1.9.2, an allocation failure was found in the function TNEFFillMapi in ytnef.c, which allows attackers to cause a denial of service via a crafted file.


4) NULL pointer dereference (CVE-ID: CVE-2017-9470)

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 file.


5) Out-of-bounds read (CVE-ID: CVE-2017-9472)

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

The vulnerability exists due to a boundary error in In ytnef 1.9.2, the SwapDWord function in lib/ytnef.c. A remote attacker can perform a denial of service (heap-based buffer over-read and application crash) via a crafted file.


6) Out-of-bounds read (CVE-ID: CVE-2017-9474)

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

The vulnerability exists due to a boundary error in In ytnef 1.9.2, the DecompressRTF function in lib/ytnef.c. A remote attacker can perform a denial of service (heap-based buffer over-read and application crash) via a crafted file.
