The fnmatch function in the GNU C Library (aka glibc or libc6) before 2.22 might allow context-dependent attackers to cause a denial of service (application crash) via a malformed pattern, which triggers an out-of-bounds read.
La función fnmatch en GNU C Library (también conocida como glibc o libc6) en versiones anteriores a 2.22 podría permitir a atacantes dependientes del contexto provocar una denegación de servicio (caída de aplicación) a través de un patrón malformado, que desencadena una lectura fuera de límites.
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.
