Title: Opera Web Browser 'dtoa()' Remote Code Execution Vulnerability
Severity: HIGH
Description:
Opera Web Browser is a browser that runs on multiple operating systems.
The browser is prone to a remote code-execution vulnerability. Specifically, this issue arises when the JavaScript engine parses strings into floating-point numbers using the 'dtoa()' function. Malicious JavaScript code may gain unauthorized access to memory, allowing the attacker to obtain sensitive information and execute arbitrary code. Failed attacks may cause denial-of-service conditions.
The attacker can exploit this issue by enticing an unsuspecting victim to view a malicious webpage.
NOTE: This issue is related to BID 35510 (Multiple BSD Distributions 'gdtoa/misc.c' Memory Corruption Vulnerability), but because of differences in the code base, it is being assigned its own record.
This issue affects Opera 10.01; other versions may also be affected.
Affected Products:
- Opera Software Opera Web Browser 10.01
