01

What, why and how

A buffer overflow was found in grub_font_construct_glyph(). A malicious crafted pf2 font can lead to an overflow when calculating the max_glyph_size value, allocating a smaller than needed buffer for the glyph, this further leads to a buffer overflow and a heap based out-of-bounds write. An attacker may use this vulnerability to circumvent the secure boot mechanism.

What

A buffer overflow was found in grub_font_construct_glyph(). A malicious crafted pf2 font can lead to an overflow when calculating the max_glyph_size value, allocating a smaller than needed buffer for the glyph, this further leads to a buffer overflow and a heap based out-of-bounds write. An attacker may use this vulnerability to circumvent the secure boot mechanism.

Why

A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().

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 → Heap-based Buffer Overflow → cause the confidentiality, integrity or availability impact described by the vendor
Attack surface
Local
Privileges required
None: unauthenticated exploitation is possible

Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-122 ↗

CWE-122: Heap-based Buffer Overflow. A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.

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.SChangedScope: The attack can affect a component governed by a different security authority.CHighConfidentiality impact: A successful attack can cause a major loss.IHighIntegrity impact: A successful attack can cause a major loss.AHighAvailability impact: A successful attack can cause a major loss.

NCSC-NL · Dutch · NCSC-2024-0334Kwetsbaarheden verholpen in Microsoft Windows

Microsoft heeft kwetsbaarheden verholpen in Windows. Een kwaadwillende kan de kwetsbaarheden misbruiken om aanvallen uit te voeren die kunnen leiden tot de volgende categorieën schade: - Denial-of-Service - Omzeilen van beveiligingsmaatregel - Manipuleren van gegevens - Verkrijgen van verhoogde rechten - Spoofing - Uitvoeren van willekeurige code (root/administrator rechten) - Uitvoeren van willekeurige code (Gebruikersrechten) - Toegang tot systeemgegevens Van de kwetsbaarheden met kenmerk CVE-2024-38106, CVE-2024-38107, CVE-2024-38178 en CVE-2024-38193 geeft Microsoft aan informatie te hebben dat deze actief zijn misbruikt. De kwetsbaarheden met kenmerk CVE-2024-38106, CVE-2024-38107 en CVE-2024-38193 bevinden zich respectievelijk in de Kernel, de Power Dependency Coördinator en de Ancillary Function Driver for WinSock en stellen een lokale, geauthenticeerde kwaadwillende in staat om zich verhoogde rechten toe te kennen en code uit te voeren met SYSTEM rechten. De kwetsbaarheid met kenmerk CVE-2024-38178 bevindt zich in de Scripting Engine en stelt een kwaadwillende in staat om willekeurige code uit te voeren met rechten van het slachtoffer. Succesvol misbruik vereist wel dat de kwaadwillende het slachtoffer misleidt om de Edge browser in 'Internet Explorer mode' laat draaien. Van de genoemde kwetsbaarheden is geen publieke Proof-of-Concept-code of exploit beschikbaar. Het vermoeden van het NCSC is echter dat deze wel op korte termijn publiek beschikbaar zal komen. Grootschalig actief misbruik is minder waarschijnlijk, vanwege de beperkende voorwaarden van misbruik. De ernstigste kwetsbaarheid heeft kenmerk CVE-2024-38063 toegewezen gekregen en bevindt zich in de wijze waarop Windows het IPv6 Protocol verwerkt. Een kwaadwillende kan zonder voorafgaande authenticatie op afstand willekeurige code uitvoeren op het kwetsbare systeem door het herhaaldelijk verzenden van speciaal geprepareerde IPv6 packets. IPv6 is standaard actief. Onderzoekers hebben Proof-of-Concept-code (PoC) gepubliceerd waarmee de kwetsbaarheid kan worden aangetoond. De PoC code vereist dat het doelwit onder controle is van de onderzoeker en veroorzaakt op dit moment hooguit een memory corruption wat resulteert in een crash van het systeem. Uitvoer van willekeurige code wordt niet bereikt. De kans op grootschalig misbruik wordt hiermee groter, maar door de beperkende voorwaarde om de PoC werkend te krijgen is deze PoC niet zondermeer grootschalig op internet in te zetten. Microsoft is niet op de hoogte dat de kwetsbaarheid actief wordt misbruikt. Microsoft adviseert om als mitigerende maatregel IPv6 uit te schakelen indien dit niet strikt noodzakelijk is. De kwetsbaarheden met kenmerk CVE-2024-21302 en CVE-2024-38202 zijn op de laatste BlackHat Conference gepubliceerd door de onderzoeker die ze ontdekt heeft. Deze kwetsbaarheden worden in de gegevens van deze maandelijkse update wel genoemd, maar in deze update worden ze niet verholpen. Microsoft geeft aan nog aan een oplossing te werken en heeft wel mitigerende maatregelen gepubliceerd, om de dreiging van misbruik zo goed als mogelijk te beperken. Zie hiervoor de referenties naar de specifieke kwetsbaarheid. De kwetsbaarheden stellen een kwaadwillende in staat om een roll-back uit te voeren van geïnstalleerde updates en zo het systeem weer kwetsbaar te maken voor oudere kwetsbaarheden, zonder dat dit ontdekt kan worden door het systeem. Voor het slachtoffer blijft het systeem voldoen aan de laatste beveiligingsupdates. Succesvol misbruik is niet eenvoudig en vereist dat de kwaadwillende over verhoogde rechten beschikt op het kwetsbare systeem. Actief misbruik zal dus vermoedelijk een volgende stap in een keten zijn door een kwaadwillende die op andere wijze toegang heeft gekregen tot het kwetsbare systeem en deze kwetsbaarheden gebruikt om permanente toegang te garanderen. ``` Windows Mark of the Web (MOTW): |----------------|------|-------------------------------------| | CVE-ID | CVSS | Impact |
