Details

An uninitialized value issue was discovered in ICU. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service. (CVE-2015-1270)

A use-after-free was discovered in the GPU process implementation in Chromium. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking the program. (CVE-2015-1272)

A use-after-free was discovered in the IndexedDB implementation in Chromium. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking the program. (CVE-2015-1276)

A use-after-free was discovered in the accessibility implemetation in Chromium. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking the program. (CVE-2015-1277)

A memory corruption issue was discovered in Skia. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via renderer crash, or execute arbitrary code with the privileges of the sandboxed render process. (CVE-2015-1280)

It was discovered that Blink did not properly determine the V8 context of a microtask in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass Content Security Policy (CSP) restrictions. (CVE-2015-1281)

Multiple integer overflows were discovered in Expat.

An issue was discovered in the CSS implementation in Blink. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass same-origin restrictions. (CVE-2015-1287)

Multiple security issues were discovered in Chromium. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to read uninitialized memory, cause a denial of service via application crash or execute arbitrary code with the privileges of the user invoking the program. (CVE-2015-1289)

A use-after-free was discovered in oxide::qt::URLRequestDelegatedJob in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking the program. (CVE-2015-1329)

A crash was discovered in the regular expression implementation in V8 in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service. (CVE-2015-5605)
