**Nome do software vulnerável e versões afetadas: Componente gráfico do Windows (versões afetadas não especificadas) Descrição: O problema está relacionado a erros no processamento de objetos na memória dentro do componente gráfico do Windows. Isso pode permitir que um invasor divulgue informações protegidas. A vulnerabilidade pode ser explorada para obter informações confidenciais e afetar o sistema. Recomendações: No momento, não há informações sobre uma versão mais recente que contenha uma correção para esta vulnerabilidade.

O problema está relacionado ao tratamento incorreto de objetos na memória, o que pode ser explorado através da execução de um aplicativo especialmente criado para esse fim, permitindo que um invasor eleve seus privilégios. Isso pode afetar o sistema.

The issue is related to memory corruption and buffer overflow, which may lead to arbitrary code execution when processing maliciously crafted web content. This can allow a remote attacker to execute arbitrary code.

The issue is related to errors in handling objects in memory by the ChakraCore JavaScript engine. This could allow a remote attacker to execute arbitrary code, potentially gaining the same user rights as the current user. If the current user has administrative rights, the attacker could take control of the affected system, enabling them to install programs, view, change, or delete data, or create new accounts with full user rights.

Multiple memory corruption issues were addressed with improved memory handling.

Multiple memory corruption issues were addressed with improved memory handling.

The issue is related to multiple integer overflows in the ` objalloc alloc` function and `objalloc alloc` macro, which can be exploited by remote attackers to cause a denial of service (crash) through vectors related to the addition of `CHUNK HEADER SIZE` to the length. This triggers a heap-based buffer overflow.
