Description
This security bulletin contains information about 3 vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2019-19590)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to integer overflow for the variable "new_token_size" in the "r_asm_massemble" function in "libr/asm/asm.c". A remote attacker can trigger integer overflow, which will result in a Use-After-Free for the buffer tokens and cause a denial of service (DoS) condition or possibly execute arbitrary code via crafted input.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Cross-site scripting (CVE-ID: CVE-2019-19547)
CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVSSv4: CVSS:4.0/AV:L/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. 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) Input validation error (CVE-ID: CVE-2019-19647)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input within the r_asm_pseudo_incbin(0 function at libr/asm/asm.c. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
