Description

This security bulletin contains information about 2 vulnerabilities.


1) Input validation error (CVE-ID: CVE-2009-5063)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows context-dependent attackers to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause a denial of service (memory leak or segmentation fault) via a JPEG image containing an iCCP chunk with a negative embedded profile length.


2) Integer overflow (CVE-ID: CVE-2011-3026)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

Integer overflow in libpng, as used in Google Chrome before 17.0.963.56, allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors that trigger an integer truncation.
