Memory leak in the __res_vinit function in the IPv6 name server management code in libresolv in GNU C Library (aka glibc or libc6) before 2.24 allows remote attackers to cause a denial of service (memory consumption) by leveraging partial initialization of internal resolver data structures.
Fuga de memoria en la función __res_vinit en el código de gestión del servidor de nombres IPv6 en libresolv en GNU C Library (también conocido como glibc o libc6) en versiones anteriores a 2.24 permite a atacantes remotos provocar una denegación de servicio (consumo de memoria) aprovechando la inicialización parcial de las estructuras internas de datos de resolución.
It was discovered that the GNU C Library incorrectly handled the strxfrm function. An attacker could use this issue to cause a denial of service or possibly execute arbitrary code. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. It was discovered that an integer overflow existed in the _IO_wstr_overflow function of the GNU C Library. An attacker could use this to cause a denial of service or possibly execute arbitrary code. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. Various other issues were also addressed.
