Vulnerability Details

CVEID: CVE-2018-17082
DESCRIPTION: PHP is vulnerable to cross-site scripting, caused by improper validation of user-supplied input by the Apache2 component. A remote attacker could exploit this vulnerability using the body of a "Transfer-Encoding: chunked" request to execute script in a victim's Web browser within the security context of the hosting Web site, once the URL is clicked. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.

CVEID: CVE-2018-14883
DESCRIPTION: PHP is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the exif_thumbnail_extract function in exif.c. By sending a specially-crafted request, a remote attacker could overflow a buffer and execute arbitrary code on the system.
CVSS Base Score: 9.8

CVEID: CVE-2018-14851
DESCRIPTION: PHP is vulnerable to a denial of service, caused by an out-of-bounds read in the exif_process_IFD_in_MAKERNOTE function in ext/exif/exif.c. By persuading a victim to open a specially-crafted file, a remote attacker could exploit this vulnerability to cause the application to crash.
