CVSS: 4.4EPSS: 0%CPEs: 28EXPL: 2CVE-2013-4332 – glibc: three integer overflows in memory allocator
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 •
CVSS: 5.0EPSS: 16%CPEs: 36EXPL: 0CVE-2013-1914 – glibc: Stack (frame) overflow in getaddrinfo() when processing entry mapping to long list of address structures
https://notcve.org/view.php?id=CVE-2013-1914
Stack-based buffer overflow in the getaddrinfo function in sysdeps/posix/getaddrinfo.c in GNU C Library (aka glibc or libc6) 2.17 and earlier allows remote attackers to cause a denial of service (crash) via a (1) hostname or (2) IP address that triggers a large number of domain conversion results. Desbordamiento de búfer basado en pila en la función getaddrinfo en sysdeps/posix/getaddrinfo.c en GNU C Library (tambien conocido como glibc o libc6) v2.17 y anteriores permite a atacantes remotos provocar una denegación de servicio (caída de la aplicación) a través de un (1) nombre de host o (2) una dirección IP que desencadenan un gran número de resultados en la conversión de dominio. It was found that getaddrinfo() did not limit the amount of stack memory used during name resolution. An attacker able to make an application resolve an attacker-controlled hostname or IP address could possibly cause the application to exhaust all stack memory and crash. Many Moxa devices suffer from command injection, cross site scripting, and outdated software vulnerabilities. • http://packetstormsecurity.com/files/164014/Moxa-Command-Injection-Cross-Site-Scripting-Vulnerable-Software.html http://rhn.redhat.com/errata/RHSA-2013-0769.html http://rhn.redhat.com/errata/RHSA-2013-1605.html http://seclists.org/fulldisclosure/2021/Sep/0 http://secunia.com/advisories/52817 http://secunia.com/advisories/55113 http://sourceware.org/bugzilla/show_bug.cgi?id=15330 http://sourceware.org/git/?p=glibc.git%3Ba=commitdiff%3Bh=1cef1b19089528db11f221e938f60b9b048945d7 http://www.mandriva • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

https://notcve.org/view.php?id=CVE-2011-2702
Integer signedness error in Glibc before 2.13 and eglibc before 2.13, when using Supplemental Streaming SIMD Extensions 3 (SSSE3) optimization, allows context-dependent attackers to execute arbitrary code via a negative length parameter to (1) memcpy-ssse3-rep.S, (2) memcpy-ssse3.S, or (3) memset-sse2.S in sysdeps/i386/i686/multiarch/, which triggers an out-of-bounds read, as demonstrated using the memcpy function. Error de signo de enteros en Glibc anterior a 2.13 y eglibc anterior a 2.13, cuando utiliza la optimización Supplemental Streaming SIMD Extensions 3 (SSSE3), permite a atacantes dependientes de contexto ejecutar código arbitrario a través de un parámetro de longitud negativo en (1) memcpy-ssse3-rep.S, (2) memcpy-ssse3.S, o (3) memset-sse2.S en sysdeps/i386/i686/multiarch/, lo que provoca una lectura fuera de rango, tal y como fue demostrado mediante el uso de la función memcpy. A patch introduced a signedness bug causing any program compiled against the vulnerable version of eglibc and using optimized functions such as memcpy_ssse3 and memcpy-ssse3-back to be potentially vulnerable to unexpected code execution. • https://www.exploit-db.com/exploits/20167 http://seclists.org/oss-sec/2011/q3/123 http://seclists.org/oss-sec/2011/q3/153 http://www.eglibc.org/cgi-bin/viewvc.cgi/trunk/libc/ChangeLog?view=markup&pathrev=10032 http://www.nodefense.org/eglibc.txt http://www.osvdb.org/80718 http://xorl.wordpress.com/2011/08/06/cve-2011-2702-eglibc-and-glibc-signedness-issue https://bugzilla.novell.com/show_bug.cgi?id=706915 https://sourceware.org/git/?p=glibc.git%3Ba=commi • CWE-94: Improper Control of Generation of Code ('Code Injection') •
