CVSS: 6.4EPSS: 0%CPEs: 5EXPL: 0CVE-2015-1473 – glibc: Stack-overflow in glibc swscanf
https://notcve.org/view.php?id=CVE-2015-1473
The ADDW macro in stdio-common/vfscanf.c in the GNU C Library (aka glibc or libc6) before 2.21 does not properly consider data-type size during a risk-management decision for use of the alloca function, which might allow context-dependent attackers to cause a denial of service (segmentation violation) or overwrite memory locations beyond the stack boundary via a long line containing wide characters that are improperly handled in a wscanf call. El macro ADDW en stdio-common/vfscanf.c en la libraría GNU C (también conocida como glibc o libc6) anterior a 2.21 no considera correctamente el tamaño de tipos de datos durante una decisión de la gestión de riesgos para utilizar en la función alloca, lo que podría permitir atacantes dependientes de contexto causar una denegación de servicio (violación de segmentación) o sobrescribir localizaciones de memoria más allá del límite de la pila a través de una línea larga que contiene caracateres anchas que se manejen incorrectamente en una llamada wscanf. A stack overflow flaw was found in glibc's swscanf() function. An attacker able to make an application call the swscanf() function could use this flaw to crash that application or, potentially, execute arbitrary code with the permissions of the user running the application. • http://openwall.com/lists/oss-security/2015/02/04/1 http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2015-2719645.html http://www.securityfocus.com/bid/72499 http://www.ubuntu.com/usn/USN-2519-1 https://sourceware.org/git/gitweb.cgi?p=glibc.git%3Ba=commit%3Bh=5bd80bfe9ca0d955bfbbc002781bc7b01b6bcb06 https://access.redhat.com/security/cve/CVE-2015-1473 https://bugzilla.redhat.com/show_bug.cgi?id=1209105 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-121: Stack-based Buffer Overflow •
CVSS: 5.1EPSS: 1%CPEs: 1EXPL: 0CVE-2013-7424 – glibc: Invalid-free when using getaddrinfo()
https://notcve.org/view.php?id=CVE-2013-7424
The getaddrinfo function in glibc before 2.15, when compiled with libidn and the AI_IDN flag is used, allows context-dependent attackers to cause a denial of service (invalid free) and possibly execute arbitrary code via unspecified vectors, as demonstrated by an internationalized domain name to ping6. Vulnerabilidad en la función getaddrinfo en glibc en versiones anteriores a 2.15, cuando es compilado con libidn y es utilizado el indicador AI_IDN, permite a atacantes dependientes de contexto provocar una denegación de servicio (liberación de memoria no válida) y posiblemente ejecutar código arbitrario a través de vectores no especificados, según lo demostrado en un nombre de dominio internacionalizado para ping6. An invalid free flaw was found in glibc's getaddrinfo() function when used with the AI_IDN flag. A remote attacker able to make an application call this function could use this flaw to execute arbitrary code with the permissions of the user running the application. Note that this flaw only affected applications using glibc compiled with libidn support. • http://rhn.redhat.com/errata/RHSA-2015-1627.html http://www.openwall.com/lists/oss-security/2015/01/29/21 http://www.securityfocus.com/bid/72710 https://bugzilla.redhat.com/show_bug.cgi?id=1186614 https://bugzilla.redhat.com/show_bug.cgi?id=981942 https://sourceware.org/bugzilla/show_bug.cgi?id=18011 https://sourceware.org/git/gitweb.cgi?p=glibc.git%3Ba=commitdiff%3Bh=2e96f1c7 https://access.redhat.com/security/cve/CVE-2013-7424 • CWE-17: DEPRECATED: Code •

https://notcve.org/view.php?id=CVE-2015-0235
Heap-based buffer overflow in the __nss_hostname_digits_dots function in glibc 2.2, and other 2.x versions before 2.18, allows context-dependent attackers to execute arbitrary code via vectors related to the (1) gethostbyname or (2) gethostbyname2 function, aka "GHOST." Desbordamiento de buffer basado en memoria dinámica en la función __nss_hostname_digits_dots en glibc 2.2, y otras versiones 2.x anteriores a 2.18, permite a atacantes dependientes de contexto ejecutar código arbitrario a través de vectores relacionados con la funciín (1) gethostbyname o (2) gethostbyname2, también conocido como 'GHOST.' A heap-based buffer overflow was found in glibc's __nss_hostname_digits_dots() function, which is used by the gethostbyname() and gethostbyname2() glibc function calls. A remote attacker able to make an application call either of these functions could use this flaw to execute arbitrary code with the permissions of the user running the application. The industrial managed switch series 852 from WAGO is affected by multiple vulnerabilities such as old software components embedded in the firmware. • https://www.exploit-db.com/exploits/35951 https://www.exploit-db.com/exploits/36421 https://github.com/aaronfay/CVE-2015-0235-test https://github.com/makelinux/CVE-2015-0235-workaround https://github.com/sUbc0ol/CVE-2015-0235 https://github.com/mikesplain/CVE-2015-0235-cookbook https://github.com/tobyzxj/CVE-2015-0235 https://github.com/adherzog/ansible-CVE-2015-0235-GHOST http://blogs.sophos.com/2015/01/29/sophos-products-and-the-ghost-vulnerability-affecting-linux http:/ • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2014-6040
GNU C Library (aka glibc) before 2.20 allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) via a multibyte character value of "0xffff" to the iconv function when converting (1) IBM933, (2) IBM935, (3) IBM937, (4) IBM939, or (5) IBM1364 encoded data to UTF-8. GNU C Library (también conocido como glibc) anterior a 2.20 permite a atacantes dependientes de contexto causar una denegación de servicio (lectura fuera de rango y caída) a través de un valor de caracteres de multibytes de '0xffff' en la función iconv cuando convierte datos codificados de (1) IBM933, (2) IBM935, (3) IBM937, (4) IBM939, o (5) IBM1364 a UTF-8. An out-of-bounds read flaw was found in the way glibc's iconv() function converted certain encoded data to UTF-8. An attacker able to make an application call the iconv() function with a specially crafted argument could use this flaw to crash that application. • http://linux.oracle.com/errata/ELSA-2015-0016.html http://secunia.com/advisories/62100 http://secunia.com/advisories/62146 http://ubuntu.com/usn/usn-2432-1 http://www.debian.org/security/2015/dsa-3142 http://www.mandriva.com/security/advisories?name=MDVSA-2014:175 http://www.openwall.com/lists/oss-security/2014/08/29/3 http://www.openwall.com/lists/oss-security/2014/09/02/1 http://www.securityfocus.com/bid/69472 https://security.gentoo.org/glsa/201602-02& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
