CVE-2015-0310 — Adobe Flash Player ASLR Bypass Vulnerability

Adobe Flash Player before 13.0.0.262 and 14.x through 16.x before 16.0.0.287 on Windows and OS X and before 11.2.202.438 on Linux does not properly restrict discovery of memory addresses, which allows attackers to bypass the ASLR protection mechanism on Windows, and have an unspecified impact on other platforms, via unknown vectors, as exploited in the wild in January 2015.

High

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

CISA KEV · May 25, 2022

How the score was calculated

Confirmed exploitation (CISA KEV)+35
EPSS 15.1% (30-day exploitation probability)+15
Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (Adobe Flash Player).
Treat as emergency remediation: the CVE is in CISA KEV (confirmed exploitation).
Apply the fixed version or the patch documented under Remediation.
Exploitation requires user interaction: tighten email/web filtering and warn affected users.
EPSS ahead of 97% of scored CVEs: prioritize it in the patch queue.
Search available logs for exploit probes matching the vulnerability class (info disclosure), errors and authentication anomalies.

Sources disagree significantly and the divergence is under review. Every score is kept with its origin. For prioritization we use 9.8 (GitHub, Inc. via GitHub Security Advisories) as a conservative provisional reference — not a definitive official score.

Ransomware use

Unknown

CISA records ransomware use only for campaigns it has confirmed, so “Unknown” means unrecorded, not ruled out. The deadline binds US federal agencies; for everyone else it is a reference date.
