A local attacker could overflow a buffer and execute arbitrary code on the system or cause a denial of service. A remote attacker could exploit this vulnerability using IDAT data with a large width to overflow a buffer and execute arbitrary code on the system or cause a denial of service. Vulnerability Details CVEID:CVE-2014-9495 DESCRIPTION: libpng is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the png_combine_row function when decompressing the IDAT_data. A remote attacker could exploit this vulnerability using a "very wide interlaced" PNG image to overflow a buffer and execute arbitrary code on the system or cause a denial of service. CVSS Base Score:9.30 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/99699 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:C/I:C/A:C) CVEID: CVE-2015-0973 DESCRIPTION: Libpng is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the png_read_IDAT_data() function. A remote attacker could exploit this vulnerability using IDAT data with a large width to overflow a buffer and execute arbitrary code on the system or cause a denial of service. CVSS Base Score: 7.5 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/100239 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P) Affected Products and Versions Notes 9.0.1 Fix Pack 3 (plus Interim Fix 1) and earlier Notes 8.5.3 Fix Pack versions 4, 5, and 6 (plus Interim Fixes) Remediation/Fixes CVE-2014-9495 and CVE-2015-0973 are also tracked as SPR PSIH9SSAHC.
