Descriptions

The 'globbing' feature in curl before version 7.51.0 has a flaw that leads to integer overflow and out-of-bounds read via user controlled input.

La funcionalidad de "globbing" en curl en versiones anteriores a la 7.51.0 tiene un error que conduce a un desbordamiento de enteros y a una lectura fuera de límites mediante entradas controladas por el usuario.

It was discovered that curl incorrectly reused client certificates when built with NSS. A remote attacker could possibly use this issue to hijack the authentication of a TLS connection. Nguyen Vu Hoang discovered that curl incorrectly handled escaping certain strings. A remote attacker could possibly use this issue to cause curl to crash, resulting in a denial of service, or possibly execute arbitrary code. Various other issues were also addressed.
