Description
This security bulletin contains information about 9 vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2011-3057)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 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/E:U/U:Green
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
Google V8, as used in Google Chrome before 17.0.963.83, allows remote attackers to cause a denial of service via vectors that trigger an invalid read operation.
2) Universal cross-site scripting (CVE-ID: CVE-2011-3058)
CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:U/U:Green
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data in EUC-JP encoding. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
3) Out-of-bounds read (CVE-ID: CVE-2011-3059)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 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/E:U/U:Green
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
Google Chrome before 18.0.1025.142 does not properly handle SVG text elements, which allows remote attackers to cause a denial of service (out-of-bounds read) via unspecified vectors.
4) Out-of-bounds read (CVE-ID: CVE-2011-3060)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 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/E:U/U:Green
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
Google Chrome before 18.0.1025.142 does not properly handle text fragments, which allows remote attackers to cause a denial of service (out-of-bounds read) via unspecified vectors.
5) Improper Certificate Validation (CVE-ID: CVE-2011-3061)
CWE-ID: CWE-295 - Improper Certificate Validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
Google Chrome before 18.0.1025.142 does not properly check X.509 certificates before use of a SPDY proxy, which might allow man-in-the-middle attackers to spoof servers or obtain sensitive information via a crafted certificate.
6) Incorrect calculation (CVE-ID: CVE-2011-3062)
CWE-ID: CWE-682 - Incorrect Calculation
CVSSv4: 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/E:U/U:Green
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
Off-by-one error in the OpenType Sanitizer in Google Chrome before 18.0.1025.142 allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted OpenType file.
7) Input validation error (CVE-ID: CVE-2011-3063)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote non-authenticated attacker to manipulate data.
Google Chrome before 18.0.1025.142 does not properly validate the renderer's navigation requests, which has unspecified impact and remote attack vectors.
8) Use-after-free (CVE-ID: CVE-2011-3064)
CWE-ID: CWE-416 - Use After Free
CVSSv4: 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/E:U/U:Green
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when processing vectors related to SVG clipping. A remote attackers can cause a denial of service or possibly have unspecified other impact.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
9) Integer overflow (CVE-ID: CVE-2011-3065)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: 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/E:U/U:Green
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
Skia, as used in Google Chrome before 18.0.1025.142, allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via unknown vectors.
