A empresa Cisco lan\u00e7ou novas vers\u00f5es do pacote antiv\u00edrus gratuito ClamAV 1.4.2 e 1.0.8, nas quais foi corrigida uma vulnerabilidade (CVE-2025-20128). A vulnerabilidade \u00e9 causada por um estouro de buffer no c\u00f3digo de an\u00e1lise de arquivos contendo conte\u00fado no formato OLE2 (Object Linking and Embedding 2), que um atacante remoto n\u00e3o autenticado pode explorar para causar uma nega\u00e7\u00e3o de servi\u00e7o. O problema se manifesta a partir da vers\u00e3o ClamAV 1.0.0 e foi identificado durante os testes de fuzzing realizados pelo projeto OSS-Fuzz. <\/p>\n

A vulnerabilidade \u00e9 causada por um estouro inteiro ao verificar limites, levando \u00e0 leitura de \u00e1reas fora do buffer alocado. O problema se manifesta ao processar arquivos que cont\u00eam conte\u00fado especialmente formatado no formato OLE2, resultando na falha do processo de varredura. H\u00e1 relatos de identifica\u00e7\u00e3o na rede de um prot\u00f3tipo de exploit que pode ser usado para ataques a sistemas de e-mail servidores<\/a> ou sistemas de compartilhamento de arquivos que utilizam ClamAV.
