Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Integer overflow (CVE-ID: CVE-2019-5085)

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

An exploitable code execution vulnerability exists in the DICOM packet-parsing functionality of LEADTOOLS libltdic.so, version 20.0.2019.3.15. A specially crafted packet can cause an integer overflow, resulting in heap corruption. An attacker can send a packet to trigger this vulnerability.


2) Out-of-bounds read (CVE-ID: CVE-2019-5090)

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

An exploitable information disclosure vulnerability exists in the DICOM packet-parsing functionality of LEADTOOLS libltdic.so, version 20.0.2019.3.15. A specially crafted packet can cause an out-of-bounds read, resulting in information disclosure. An attacker can send a packet to trigger this vulnerability.


3) Infinite loop (CVE-ID: CVE-2019-5091)

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

An exploitable denial-of-service vulnerability exists in the Dicom-packet parsing functionality of LEADTOOLS libltdic.so version 20.0.2019.3.15. A specially crafted packet can cause an infinite loop, resulting in a denial of service. An attacker can send a packet to trigger this vulnerability.


4) Out-of-bounds write (CVE-ID: CVE-2019-5092)

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

An exploitable heap out of bounds write vulnerability exists in the UI tag parsing functionality of the DICOM image format of LEADTOOLS 20.0.2019.3.15. A specially crafted DICOM image can cause an offset beyond the bounds of a heap allocation to be written, potentially resulting in code execution. An attacker can specially craft a DICOM image to trigger this vulnerability.


5) Integer overflow (CVE-ID: CVE-2019-5093)

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

An exploitable code execution vulnerability exists in the DICOM network response functionality of LEADTOOLS libltdic.so version 20.0.2019.3.15. A specially crafted packet can cause an integer overflow, resulting in heap corruption. An attacker can send a packet to trigger this vulnerability.


6) Out-of-bounds write (CVE-ID: CVE-2019-5154)

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

An exploitable heap overflow vulnerability exists in the JPEG2000 parsing functionality of LEADTOOLS 20.0.2019.3.15. A specially crafted J2K image file can cause an out of bounds write of a null byte in a heap buffer, potentially resulting in code execution. An attack can specially craft a J2K image to trigger this vulnerability.
