Summary
Heap buffer overflow in vp8 encoding in libvpx in Google Chrome prior to 117.0.5938.132 and libvpx 1.13.1 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)
Remediation
The CVE's listed above affect the PostgresSQL pgadmin tool. If you have installed this tool, not required by EcoStruxure™ Power Operation 2024, we recommend you uninstall it from your EPO server and client machines.We strongly recommend customers take the following actions:• If waveform analysis and ETAP simulation features are not used, uninstall PostgreSQLOR• For those customers using waveform analysis and ETAP simulation features, we recommend all deployments of EPO only accept connections from localhost in PostgresSQL. Contact customer care for information on how to modify PostgreSQL. Further, we recommend you manually uninstall PostgreSQL 14.10 and update to PostgreSQL 14.17 or higher. EcoStruxure™ Power Operation 2024 CU2 includes an updated version of PostgreSQL and is available for download here: https://community.se.com/t5/EcoStruxure-Power-Operation/v2024-Release-amp-Updates-Install-Procedure/m-p/478928/thread-id/6997#M6997

What, why and how

Google Chromium libvpx contains a heap buffer overflow vulnerability in vp8 encoding that allows a remote attacker to potentially exploit heap corruption via a crafted HTML page. This vulnerability could impact web browsers using libvpx, including but not limited to Google Chrome.

What

Google Chromium libvpx contains a heap buffer overflow vulnerability in vp8 encoding that allows a remote attacker to potentially exploit heap corruption via a crafted HTML page. This vulnerability could impact web browsers using libvpx, including but not limited to Google Chrome.

Why

A bounds error lets data be written beyond the intended memory region, potentially corrupting control data.

How

An attacker operating through a network path may attempt exploitation without authentication after a user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
Confirmed in the wild

CISA added this CVE to its Known Exploited Vulnerabilities catalogue on 2023-10-02.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
Reference recorded

A structured CVE source labels at least one public reference as exploit material. BlackTree has not independently validated that it is safe, reliable or weaponised.
