CVE-2024-47537

Estado: ModificadaAlta (8.6)—

GStreamer is a library for constructing graphs of media-handling components. The program attempts to reallocate the memory pointed to by stream->samples to accommodate stream->n_samples + samples_count elements of type QtDemuxSample. The problem is that samples_count is read from the input file. And if this value is big enough, this can lead to an integer overflow during the addition. As a consequence, g_try_renew might allocate memory for a significantly smaller number of elements than intended. Following this, the program iterates through samples_count elements and attempts to write samples_count number of elements, potentially exceeding the actual allocated memory size and causing an OOB-write. This vulnerability is fixed in 1.24.10.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Integer overflow en lectura de archivo local (AV:L) permite OOB-write, causando ejecución de código con privilegios elevados. CWE-190 (integer overflow) y CWE-787 (buffer overflow) lo sustentan.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.

Como consecuencia, g_try_renew podría asignar memoria para una cantidad significativamente menor de elementos de lo previsto.
