Stack-based buffer overflow in string/strcoll_l.c in the GNU C Library (aka glibc or libc6) 2.17 and earlier allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long string that triggers a malloc failure and use of the alloca function.

CVSS: 6.8EPSS: 0%CPEs: 27EXPL: 0CVE-2013-4237 – glibc: Buffer overwrite when using readdir_r on file systems returning file names longer than NAME_MAX characters
https://notcve.org/view.php?id=CVE-2013-4237
sysdeps/posix/readdir_r.c in the GNU C Library (aka glibc or libc6) 2.18 and earlier allows context-dependent attackers to cause a denial of service (out-of-bounds write and crash) or possibly execute arbitrary code via a crafted (1) NTFS or (2) CIFS image. sysdeps/posix/readdir_r.c en GNU C Library (también conocido como glibc o libc6) 2.18 y anteriores permite a atacantes dependientes del contexto provocar una denegación de servicio (escritura fuera de límites y cuelgue) o posiblemente ejecutar código arbitrario a través de (1) NTFS o (2) una imagen CIFS manipulada. An out-of-bounds write flaw was found in the way the glibc's readdir_r() function handled file system entries longer than the NAME_MAX character constant. A remote attacker could provide a specially crafted NTFS or CIFS file system that, when processed by an application using readdir_r(), would cause that application to crash or, potentially, allow the attacker to execute arbitrary code with the privileges of the user running the application. • http://secunia.com/advisories/55113 http://www.mandriva.com/security/advisories?name=MDVSA-2013:283 http://www.openwall.com/lists/oss-security/2013/08/12/8 http://www.securityfocus.com/bid/61729 http://www.ubuntu.com/usn/USN-1991-1 https://bugzilla.redhat.com/show_bug.cgi?id=995839 https://security.gentoo.org/glsa/201503-04 https://sourceware.org/bugzilla/show_bug.cgi?id=14699 https://sourceware.org/git/gitweb.cgi?p=glibc.git%3Ba=commitdiff%3Bh=91ce40854d0b7f865cf5024ef95a8026 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2013-4332
Multiple integer overflows in malloc/malloc.c in the GNU C Library (aka glibc or libc6) 2.18 and earlier allow context-dependent attackers to cause a denial of service (heap corruption) via a large value to the (1) pvalloc, (2) valloc, (3) posix_memalign, (4) memalign, or (5) aligned_alloc functions. Múltiples desbordamientos de enteros en malloc/malloc.c de GNU C Library (también conocida como glibc o libc6) 2.18 y anteriores versiones permite a atacantes dependientes del contexto provocar una denegación de servicio (corrupción de memoria dinámica) a través de un valor largo de funciones (1) pvalloc, (2) valloc, (3) posix_memalign, (4) memalign, o (5) aligned_alloc. Multiple integer overflow flaws, leading to heap-based buffer overflows, were found in glibc's memory allocator functions (pvalloc, valloc, and memalign). If an application used such a function, it could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. • http://rhn.redhat.com/errata/RHSA-2013-1411.html http://rhn.redhat.com/errata/RHSA-2013-1605.html http://secunia.com/advisories/55113 http://www.mandriva.com/security/advisories?name=MDVSA-2013:283 http://www.mandriva.com/security/advisories?name=MDVSA-2013:284 http://www.openwall.com/lists/oss-security/2013/09/12/6 http://www.securityfocus.com/bid/62324 http://www.ubuntu.com/usn/USN-1991-1 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2013-4332 https:// • CWE-189: Numeric Errors CWE-190: Integer Overflow or Wraparound •

Cyrus SASL 2.1.23, 2.1.26, and earlier does not properly handle when a NULL value is returned upon an error by the crypt function as implemented in glibc 2.17 and later, which allows remote attackers to cause a denial of service (thread crash and consumption) via (1) an invalid salt or, when FIPS-140 is enabled, a (2) DES or (3) MD5 encrypted password, which triggers a NULL pointer dereference. SASL de Cyrus, 2.1.23, 2.1.26 y anteriores no trabaja correctamente cuando un valor NULL se devuelve a un error de la función crypt como se aplica en glibc 2.17 y posteriores, lo que permite a atacantes remotos provocar una denegación de servicio (caída de hilo y el consumo) a través de una "salt" no válido o, cuando FIPS-140 está activado, a contraseñas cifradas con DES o MD5, lo que desencadena una referencia a un puntero NULL • http://git.cyrusimap.org/cyrus-sasl/commit/?id=dedad73e5e7a75d01a5f3d5a6702ab8ccd2ff40d http://security.gentoo.org/glsa/glsa-201309-01.xml http://www.debian.org/security/2015/dsa-3368 http://www.openwall.com/lists/oss-security/2013/07/12/3 http://www.openwall.com/lists/oss-security/2013/07/12/6 http://www.openwall.com/lists/oss-security/2013/07/13/1 http://www.openwall.com/lists/oss-security/2013/07/15/1 http://www.ubuntu.com/usn/USN-2755-1 https://www • CWE-189: Numeric Errors •

https://notcve.org/view.php?id=CVE-2013-4788
The PTR_MANGLE implementation in the GNU C Library (aka glibc or libc6) 2.4, 2.17, and earlier, and Embedded GLIBC (EGLIBC) does not initialize the random value for the pointer guard, which makes it easier for context-dependent attackers to control execution flow by leveraging a buffer-overflow vulnerability in an application and using the known zero value pointer guard to calculate a pointer address. La implementación PTR_MANGLE en la GNU C Library (librería también conocida como glibc o libc6) 2.4, 2.17 y versiones anteriores y Embedded GLIBC (EGLIBC) no inicia el valor aleatorio para la guardia de puntero, lo que facilita a atacantes dependientes del contexto controlar la ejecución de flujo aprovechando una vulnerabilidad de desbordamiento de búfer en una aplicación y utilizando el valor cero conocido guardia de puntero para calcular la dirección de puntero. • https://www.exploit-db.com/exploits/28657 http://hmarco.org/bugs/CVE-2013-4788.html http://seclists.org/fulldisclosure/2015/Sep/23 http://www.mandriva.com/security/advisories?name=MDVSA-2013:283 http://www.mandriva.com/security/advisories?name=MDVSA-2013:284 http://www.openwall.com/lists/oss-security/2013/07/15/9 http://www.securityfocus.com/bid/61183 https://security.gentoo.org/glsa/201503-04 • CWE-20: Improper Input Validation •
