COMPLETE Summary
Opera before 11.64 does not properly allocate memory for URL strings, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted string.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

NASL family Gentoo Local Security Checks NASL id GENTOO_GLSA-201206-03.NASL description The remote host is affected by the vulnerability described in GLSA-201206-03 (Opera: Multiple vulnerabilities) Multiple vulnerabilities have been discovered in Opera. Please review the CVE identifiers referenced below for details. Impact : A remote attacker could entice a user to open a specially crafted web page, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition. A remote attacker may be able to: trick users into downloading and executing arbitrary files, bypass intended access restrictions, spoof trusted content, spoof URLs, bypass the Same Origin Policy, obtain sensitive information, force subscriptions to arbitrary feeds, bypass the popup blocker, bypass CSS filtering, conduct cross-site scripting attacks, or have other unknown impact. A local attacker could perform symlink attacks to overwrite arbitrary files with the privileges of the user running the application or possibly obtain sensitive information. A physically proximate attacker may be able to access an email account. Workaround : There is no known workaround at this time. last seen 2020-06-01 modified 2020-06-02 plugin id 59631 published 2012-06-21 reporter This script is Copyright (C) 2012-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/59631 title GLSA-201206-03 : Opera: Multiple vulnerabilities code # # (C) Tenable Network Security, Inc. # # The descriptive text and package checks in this plugin were # extracted from Gentoo Linux Security Advisory GLSA 201206-03. # # The advisory text is Copyright (C) 2001-2019 Gentoo Foundation, Inc. # and licensed under the Creative Commons - Attribution / Share Alike # license.
