Cloudflare version of zlib library was found to be vulnerable to memory corruption issues affecting the deflation algorithm implementation (deflate.c). The issues resulted from improper input validation and heap-based buffer overflow.
A local attacker could exploit the problem during compression using a crafted malicious file potentially leading to denial of service of the software.
Patches: The issue has been patched in commit 8352d10 https://github.com/cloudflare/zlib/commit/8352d108c05db1bdc5ac3bdf834dad641694c13c . The upstream repository is not affected.

| Summary | (es) Se descubrió que la versión Cloudflare de la librería zlib era vulnerable a problemas de corrupción de memoria que afectan la implementación del algoritmo de deflación (deflate.c). Los problemas se debieron a una validación de entrada incorrecta y a un desbordamiento de búfer de almacenamiento dinámico. Un atacante local podría aprovechar el problema durante la compresión utilizando un archivo malicioso manipulado que podría provocar una denegación de servicio del software. Parches: el problema se solucionó en el commit 8352d10 https://github.com/cloudflare/zlib/commit/8352d108c05db1bdc5ac3bdf834dad641694c13c. El repositorio ascendente no se ve afectado. | |
