Description
This security bulletin contains information about 16 secuirty vulnerabilities.
1) Data Handling (CVE-ID: CVE-2019-11070)
The vulnerability allows a remote non-authenticated attacker to manipulate data.
WebKitGTK and WPE WebKit prior to version 2.24.1 failed to properly apply configured HTTP proxy settings when downloading livestream video (HLS, DASH, or Smooth Streaming), an error resulting in deanonymization. This issue was corrected by changing the way livestreams are downloaded.
2) Buffer overflow (CVE-ID: CVE-2019-6201)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing maliciously crafted web content. A remote attacker can trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Spoofing attack (CVE-ID: CVE-2019-6251)
The disclosed vulnerability allows a remote attacker to perform spoofing attack.The weakness exists due to improper parsing of specific HTTP content. A remote attacker can trick the victim to follow a specially crafted link and perform a spoofing attack.
4) Use-after-free (CVE-ID: CVE-2019-7285)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when processing maliciously crafted web content. A remote attacker can send a specially crafted request and execute arbitrary code on the target system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
5) Information disclosure (CVE-ID: CVE-2019-7292)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to improper input validation when processing maliciously crafted web content. A remote attacker can disclose process memory.
6) Cross-site scripting (CVE-ID: CVE-2019-8503)
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. 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.
7) Type Confusion (CVE-ID: CVE-2019-8506)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a type confusion error when processing maliciously crafted web content. A remote attacker can trigger a type confusion error and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
8) Origin validation error (CVE-ID: CVE-2019-8515)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to the affected software does not properly verify that the source of data or communication is valid when processing maliciously crafted web content. A remote attacker can disclose sensitive user information from another domain.
9) Buffer overflow (CVE-ID: CVE-2019-8524)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing maliciously crafted web content. A remote attacker can trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
10) Buffer overflow (CVE-ID: CVE-2019-8535)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing maliciously crafted web content. A remote attacker can trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
11) Buffer overflow (CVE-ID: CVE-2019-8536)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing maliciously crafted web content. A remote attacker can trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
12) Buffer overflow (CVE-ID: CVE-2019-8544)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing maliciously crafted web content. A remote attacker can trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
13) Cross-site scripting (CVE-ID: CVE-2019-8551)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
