3) Buffer overflow

EUVDB-ID: #VU23911

Risk: High

CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-5311

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

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

The vulnerability exists in the "ibImaging/SgiRleDecode.c" file due to a boundary error when processing an SGI image. A remote attacker can trigger memory corruption and execute arbitrary code on the target system.

4) Buffer overflow

EUVDB-ID: #VU24205

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-19911

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

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

The vulnerability exists when processing FPX images due to the "FpxImagePlugin.py" calls the range function on an unvalidated 32-bit integer if the number of bands is large. A remote attacker can trigger memory corruption and cause a denial of service condition on the target system.

On Windows running 32-bit Python, this results in an OverflowError or MemoryError due to the 2 GB limit. However, on Linux running 64-bit Python this results in the process being terminated by the OOM killer.

Mitigation

Update the affected package to version: 4.0.0-4+deb9u1, 5.4.1-2+deb10u1
