CVSS: 7.5EPSS: 6%CPEs: 2EXPL: 1CVE-2015-8877 – gd: gdImageScaleTwoPass function in gd_interpolation.c uses inconsistent allocate and free approaches
https://notcve.org/view.php?id=CVE-2015-8877
The gdImageScaleTwoPass function in gd_interpolation.c in the GD Graphics Library (aka libgd) before 2.2.0, as used in PHP before 5.6.12, uses inconsistent allocate and free approaches, which allows remote attackers to cause a denial of service (memory consumption) via a crafted call, as demonstrated by a call to the PHP imagescale function. La función gdImageScaleTwoPass en gd_interpolation.c en el GD Graphics Library (también conocido como libgd) en versiones anteriores a 2.2.0, como es utilizado en PHP en versiones anteriores a 5.6.12, usa asignaciones inconsistentes y enfoques libres, lo que permite a atacantes remotos provocar una denegación del servicio (consumo de memoria) a través de una llamada manipulada, según lo demostrado mediante una llamada a la función PHP imagescale. • http://rhn.redhat.com/errata/RHSA-2016-2750.html http://www.debian.org/security/2016/dsa-3587 http://www.php.net/ChangeLog-5.php http://www.ubuntu.com/usn/USN-2987-1 https://bugs.php.net/bug.php?id=70064 https://github.com/libgd/libgd/commit/4751b606fa38edc456d627140898a7ec679fcc24 https://github.com/libgd/libgd/issues/173 https://access.redhat.com/security/cve/CVE-2015-8877 https://bugzilla.redhat.com/show_bug.cgi?id=1338907 • CWE-399: Resource Management Errors CWE-772: Missing Release of Resource after Effective Lifetime •

The exif_process_IFD_in_JPEG function in ext/exif/exif.c in PHP before 5.5.35, 5.6.x before 5.6.21, and 7.x before 7.0.6 does not validate IFD sizes, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via crafted header data. La función exif_process_IFD_in_JPEG en ext/exif/exif.c en PHP en versiones anteriores a 5.5.35, 5.6.x en versiones anteriores a 5.6.21 y 7.x en versiones anteriores a 7.0.6 no valida tamaños IFD, lo que permite a atacantes remotos provocar una denegación de servicio (lectura fuera de límites) o posiblemente tener otro impacto no especificado a través de datos de cabecera manipulados. • http://lists.fedoraproject.org/pipermail/package-announce/2016-May/183736.html http://lists.opensuse.org/opensuse-updates/2016-05/msg00086.html http://lists.opensuse.org/opensuse-updates/2016-06/msg00027.html http://php.net/ChangeLog-5.php http://php.net/ChangeLog-7.php http://rhn.redhat.com/errata/RHSA-2016-2750.html http://www.debian.org/security/2016/dsa-3602 http://www.openwall.com/lists/oss-security/2016/05/05/21 http://www.securityfocus.com/bid/89844 https:/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •

The odbc_bindcols function in ext/odbc/php_odbc.c in PHP before 5.6.12 mishandles driver behavior for SQL_WVARCHAR columns, which allows remote attackers to cause a denial of service (application crash) in opportunistic circumstances by leveraging use of the odbc_fetch_array function to access a certain type of Microsoft SQL Server table.
