2) Out-of-bounds read

EUVDB-ID: #VU29437

Risk: Medium

CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2020-11538

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

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the parsing of SGI image files in "libImaging/SgiRleDecode.c". A remote attacker can create a specially crafted SGI file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.

Mitigation

4) Out-of-bounds read

EUVDB-ID: #VU29439

Risk: Medium

CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2020-10378

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

Exploit availability: No

Description

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

The vulnerability exists due to an out-of-bounds read in "libImaging/PcxDecode.c" that occurs when reading PCX files where state->shuffle is instructed to read beyond state->buffer. A remote attacker can create a specially crafted PCX file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system. 

Mitigation

Install update from vendor's website.
