Descriptions

The function `read_data()` in security.c in curl before version 7.51.0 is vulnerable to memory double free.

La función "read_data()" en security.c en curl en versiones anteriores a la 7.51.0 es vulnerable a una doble liberación (double free) de memoria.

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.
