Summary
Heap out-of-bound read in ParseJSS in VideoLAN VLC due to missing check of string length allows attackers to read heap uninitialized data via a crafted subtitles file.
Remediation
The problem is corrected in the following product versions: ABB Ability Camera Connect 1.5.0.15 The 3rd party component has already been updated. The easiest path to mitigate the problem is an update of just VLC Media Player by the customer. ABB recommends that customers apply the update at earliest convenience. It is also possible to update to the latest Version of Camera Connect.

01
What, why and how
Heap out-of-bound read in ParseJSS in VideoLAN VLC due to missing check of string length allows attackers to read heap uninitialized data via a crafted subtitles file.
What
Heap out-of-bound read in ParseJSS in VideoLAN VLC due to missing check of string length allows attackers to read heap uninitialized data via a crafted subtitles file.
Why
The product reads data past the end, or before the beginning, of the intended buffer.
How
An attacker operating through local access 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.No confirmed evidence
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
Public PoC / exploit material ?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.None recorded
No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
Likely attack path
local access → Out-of-bounds Read → cause the confidentiality, integrity or availability impact described by the vendor

Weakness ?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-125: Out-of-bounds Read. The product reads data past the end, or before the beginning, of the intended buffer.

Post-exploitation / living off the land
The issue can support a local privilege or sandbox boundary transition; normal system utilities may then be available in the gained context.
