Ubuntu vendor package status

Canonical’s release and source-package findings are shown separately from local repository availability.

2 package states
Repository candidate not checked

A published vendor fix does not prove that a matching update is enabled and installable on a particular asset. Confirm the local package candidate before scheduling remediation.

01

What, why and how

An out-of-bounds read was addressed with improved bounds checking. This issue is fixed in Safari 17.6, iOS 16.7.9 and iPadOS 16.7.9, iOS 17.6 and iPadOS 17.6, macOS Sonoma 14.6, tvOS 17.6, visionOS 1.3, watchOS 10.6. Processing maliciously crafted web content may lead to an unexpected process crash.

An out-of-bounds read was addressed with improved bounds checking. This issue is fixed in Safari 17.6, iOS 16.7.9 and iPadOS 16.7.9, iOS 17.6 and iPadOS 17.6, macOS Sonoma 14.6, tvOS 17.6, visionOS 1.3, watchOS 10.6. Processing maliciously crafted web content may lead to an unexpected process crash.

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 disrupt the affected service.

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 → disrupt the affected service
Attack surface
Local
Privileges required
None: unauthenticated exploitation is possible
User interaction
Required interaction required
Attack complexity
Low: no specialised conditions are recorded
Security boundary
Unchanged: impact remains within the vulnerable component's security authority
Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-125

CWE-125: Out-of-bounds Read. The product reads data past the end, or before the beginning, of the intended buffer.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.
CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

AVLocalAttack vector: The attacker needs local access to the vulnerable system.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRNonePrivileges required: The attacker does not need an account or existing privileges.UIRequiredUser interaction: Another user must perform an action for exploitation to succeed.SUnchangedScope: The security impact remains within the vulnerable component's authority.CNoneConfidentiality impact: No direct loss is represented by this metric.INoneIntegrity impact: No direct loss is represented by this metric.AHighAvailability impact: A successful attack can cause a major loss.
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.

NCSC-NL · Dutch · NCSC-2024-0320Kwetsbaarheden verholpen in Apple MacOS

Een kwaadwillende kan de kwetsbaarheden misbruiken om een beveiligingsmaatregel te omzeilen, zichzelf verhoogde rechten toe te kennen, toegang te krijgen tot gevoelige gegevens, willekeurige code uit te voeren, mogelijk met kernel-rechten of een Denial-of-Service te veroorzaken. Voor succesvol misbruik moet de kwaadwillende het slachtoffer misleiden een malafide app te installeren en draaien, of een malafide link te volgen. Voor het uitvoeren van willekeurige code met kernel-rechten moet de kwaadwillende reeds beschikken over verhoogde rechten op het kwetsbare systeem.

Een kwaadwillende kan de kwetsbaarheden misbruiken om aanvallen uit te voeren die kunnen leiden tot een Denial-of-Service, toegang tot systeemgegevens of toegang tot gevoelige gegevens. Om toegang te krijgen tot gevoelige gegevens, moet de kwaadwillende fysieke toegang hebben tot het kwetsbare systeem. Om een Denial-of-Service te veroorzaken, of systeemgegevens te bemachtigen moet de kwaadwillende het slachtoffer misleiden een malafide app te installeren en draaien.
