Description

This security bulletin contains information about 3 vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2020-26269)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to an out-of-bounds read in filesystem glob matching in GetMatchingPaths when parsing crafted filesystem path patterns. A local user can invoke glob matching on a crafted path to cause a denial of service.

The issue occurs because directory index assumptions in the parallel implementation are not verified under certain scenarios.


2) Input validation error (CVE-ID: CVE-2020-15266)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to improper input validation in tf.image.crop_and_resize when processing a boxes argument with very large values. A remote attacker can supply a specially crafted boxes argument to cause a denial of service.


3) Out-of-bounds read (CVE-ID: CVE-2020-15265)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to an out-of-bounds read in tf.quantization.quantize_and_dequantize when processing an invalid axis value. A remote attacker can pass a specially crafted axis value to cause a denial of service.

In normal builds, the dimension check is compiled out, which can lead to a segmentation fault.
