A flaw was found in chromium-browser. A use-after-free vulnerability in ANGLE allows a remote attacker to execute arbitrary code outside the sandbox. This can be exploited by enticing a user to visit a specially crafted HTML page, leading to a complete compromise of the affected system.
A flaw was found in ANGLE, a component of Google Chrome. This out-of-bounds read vulnerability allows a remote attacker to read memory outside of the browser's security sandbox. The flaw can be exploited by enticing a user to visit a specially crafted HTML page. The primary consequence is the unauthorized disclosure of sensitive information.

A flaw was found in ANGLE in Google Chrome. A remote attacker could exploit an out-of-bounds read vulnerability by enticing a user to visit a specially crafted HTML page. This could potentially allow the attacker to read memory outside of the browser's security sandbox, leading to information disclosure.
A flaw was found in ANGLE, a component of Google Chrome. This out-of-bounds read vulnerability could allow a remote attacker, who has already compromised the browser's renderer process, to potentially execute arbitrary code outside of the browser's security sandbox. This exploitation occurs when a user visits a specially crafted HTML page.
A flaw was found in ANGLE, a component of Google Chrome. This out-of-bounds write vulnerability allows a remote attacker to potentially execute arbitrary code. By tricking a user into visiting a specially crafted HTML page, an attacker could bypass the browser's security sandbox and execute malicious code on the system.
A flaw was found in ANGLE, a component of Google Chrome. A remote attacker who has compromised the renderer process could exploit a use-after-free vulnerability by crafting a malicious HTML page. This could potentially allow the attacker to execute arbitrary code outside of the sandbox, leading to a compromise of the system.
A flaw was found in Chromium's ANGLE component. A remote attacker could exploit a buffer overflow vulnerability by enticing a user to visit a specially crafted HTML page. This could lead to the execution of arbitrary code outside the browser's security sandbox, potentially compromising the affected system.

Successful exploitation relies on user interaction, specifically convincing an end user to render malicious graphics or web content within a client application that incorporates the ANGLE translation layer, such as Chromium or WebKitGTK. Server installations operating in headless environments or lacking graphical desktop packages are not exposed to this issue in standard deployment configurations.",

In Red Hat Enterprise Linux, affected WebKit rendering components are primarily utilized by graphical desktop applications rather than default headless server workloads. Consequently, exposure is limited to installations where desktop environments are deployed and users process untrusted external web content.",

In typical Red Hat Enterprise Linux installations, standard browser packages such as Firefox are unaffected as they do not incorporate the flawed graphics subsystem. Any residual risk in applications utilizing affected web rendering libraries is constrained by user privileges and requires convincing a local user to view hostile web content.",

In Red Hat Enterprise Linux, the impacted rendering components are primarily utilized by graphical desktop applications and embedded WebKitGTK consumers, rather than default server deployments. Exploitation relies on convincing a user to open an untrusted webpage or document. Standard headless server installations that do not run graphical or web-rendering workloads face minimal exposure.",

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.
Vulnerability timeline
Sightings and recorded dates, grouped by day · UTC
How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
