CVE-2015-8868

Desbordamiento de buffer basado en memoria dinámica en la función ExponentialFunction::ExponentialFunction en Poppler en versiones anteriores a 0.40.0 permite a atacantes remotos provocar una denegación de servicio (corrupción de memoria y caída) o posiblemente ejecutar código arbitrario a través de un modo blend no válido en el diccionario ExtGState en un documento PDF manipulado.

A heap-buffer overflow was found in the poppler library. An attacker could create a malicious PDF file that would cause applications that use poppler (such as Evince) to crash or, potentially, execute arbitrary code when opened.

It was discovered that the poppler pdfseparate tool incorrectly handled certain filenames. A local attacker could use this issue to cause the tool to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only applied to Ubuntu 12.04 LTS. It was discovered that poppler incorrectly parsed certain malformed PDF documents. If a user or automated system were tricked into opening a crafted PDF file, an attacker could cause a denial of service or possibly execute arbitrary code with privileges of the user invoking the program. Various other issues were also addressed.
