CVE-2018-6198 2 Canonical, W3m Project 2 Ubuntu Linux, W3m 2019-10-02 3.3 LOW 4.7 MEDIUM
w3m through 0.5.3 does not properly handle temporary files when the ~/.w3m directory is unwritable, which allows a local attacker to craft a symlink attack to overwrite arbitrary files.
CVE-2018-6196 2 Canonical, W3m Project 2 Ubuntu Linux, W3m 2019-10-02 5.0 MEDIUM 7.5 HIGH
w3m through 0.5.3 is prone to an infinite recursion flaw in HTMLlineproc0 because the feed_table_block_tag function in table.c does not prevent a negative indent value.
CVE-2018-5711 3 Canonical, Debian, Php 3 Ubuntu Linux, Debian Linux, Php 2019-10-02 4.3 MEDIUM 5.5 MEDIUM
gd_gif_in.c in the GD Graphics Library (aka libgd), as used in PHP before 5.6.33, 7.0.x before 7.0.27, 7.1.x before 7.1.13, and 7.2.x before 7.2.1, has an integer signedness error that leads to an infinite loop via a crafted GIF file, as demonstrated by a call to the imagecreatefromgif or imagecreatefromstring PHP function. This is related to GetCode_ and gdImageCreateFromGifCtx.
CVE-2018-5358 2 Canonical, Imagemagick 2 Ubuntu Linux, Imagemagick 2019-10-02 4.3 MEDIUM 6.5 MEDIUM
ImageMagick 7.0.7-22 Q16 has memory leaks in the EncodeImageAttributes function in coders/json.c, as demonstrated by the ReadPSDLayersInternal function in coders/psd.c.
CVE-2018-5357 2 Canonical, Imagemagick 2 Ubuntu Linux, Imagemagick 2019-10-02 4.3 MEDIUM 6.5 MEDIUM
ImageMagick 7.0.7-22 Q16 has memory leaks in the ReadDCMImage function in coders/dcm.c.
CVE-2018-5247 2 Canonical, Imagemagick 2 Ubuntu Linux, Imagemagick 2019-10-02 4.3 MEDIUM 6.5 MEDIUM
In ImageMagick 7.0.7-17 Q16, there are memory leaks in ReadRLAImage in coders/rla.c.
CVE-2018-5246 2 Canonical, Imagemagick 2 Ubuntu Linux, Imagemagick 2019-10-02 4.3 MEDIUM 6.5 MEDIUM
In ImageMagick 7.0.7-17 Q16, there are memory leaks in ReadPATTERNImage in coders/pattern.c.
CVE-2018-5185 4 Canonical, Debian, Mozilla and 1 more 10 Ubuntu Linux, Debian Linux, Thunderbird and 7 more 2019-10-02 4.3 MEDIUM 6.5 MEDIUM
Plaintext of decrypted emails can leak through by user submitting an embedded form. This vulnerability affects Thunderbird ESR < 52.8 and Thunderbird < 52.8.
CVE-2018-5175 2 Canonical, Mozilla 2 Ubuntu Linux, Firefox 2019-10-02 4.3 MEDIUM 6.1 MEDIUM
A mechanism to bypass Content Security Policy (CSP) protections on sites that have a "script-src" policy of "'strict-dynamic'". If a target website contains an HTML injection flaw an attacker could inject a reference to a copy of the "require.js" library that is part of Firefox's Developer Tools, and then use a known technique using that library to bypass the CSP restrictions on executing injected scripts. This vulnerability affects Firefox < 60.
CVE-2018-5166 2 Canonical, Mozilla 2 Ubuntu Linux, Firefox 2019-10-02 5.0 MEDIUM 7.5 HIGH
WebExtensions can use request redirection and a "filterReponseData" filter to bypass host permission settings to redirect network traffic and access content from a host for which they do not have explicit user permission. This vulnerability affects Firefox < 60.
CVE-2018-5163 2 Canonical, Mozilla 2 Ubuntu Linux, Firefox 2019-10-02 5.1 MEDIUM 8.1 HIGH
If a malicious attacker has used another vulnerability to gain full control over a content process, they may be able to replace the alternate data resources stored in the JavaScript Start-up Bytecode Cache (JSBC) for other JavaScript code. If the parent process then runs this replaced code, the executed script would be run with the parent process' privileges, escaping the sandbox on content processes. This vulnerability affects Firefox < 60.
CVE-2018-5162 4 Canonical, Debian, Mozilla and 1 more 10 Ubuntu Linux, Debian Linux, Thunderbird and 7 more 2019-10-02 5.0 MEDIUM 7.5 HIGH
Plaintext of decrypted emails can leak through the src attribute of remote images, or links. This vulnerability affects Thunderbird ESR < 52.8 and Thunderbird < 52.8.
CVE-2018-5152 2 Canonical, Mozilla 2 Ubuntu Linux, Firefox 2019-10-02 4.3 MEDIUM 6.5 MEDIUM
WebExtensions with the appropriate permissions can attach content scripts to Mozilla sites such as accounts.firefox.com and listen to network traffic to the site through the "webRequest" API. For example, this allows for the interception of username and an encrypted password during login to Firefox Accounts. This issue does not expose synchronization traffic directly and is limited to the process of user login to the website and the data displayed to the user once logged in. This vulnerability affects Firefox < 60.
CVE-2018-5142 2 Canonical, Mozilla 2 Ubuntu Linux, Firefox 2019-10-02 5.0 MEDIUM 5.3 MEDIUM
If Media Capture and Streams API permission is requested from documents with "data:" or "blob:" URLs, the permission notifications do not properly display the originating domain. The notification states "Unknown protocol" as the requestee, leading to user confusion about which site is asking for this permission. This vulnerability affects Firefox < 59.
CVE-2018-5117 4 Canonical, Debian, Mozilla and 1 more 11 Ubuntu Linux, Debian Linux, Firefox and 8 more 2019-10-02 5.0 MEDIUM 5.3 MEDIUM
If right-to-left text is used in the addressbar with left-to-right alignment, it is possible in some circumstances to scroll this text to spoof the displayed URL. This issue could result in the wrong URL being displayed as a location, which can mislead users to believe they are on a different site than the one loaded. This vulnerability affects Thunderbird < 52.6, Firefox ESR < 52.6, and Firefox < 58.
CVE-2018-5105 2 Canonical, Mozilla 2 Ubuntu Linux, Firefox 2019-10-02 7.2 HIGH 7.8 HIGH
WebExtensions can bypass user prompts to first save and then open an arbitrarily downloaded file. This can result in an executable file running with local user privileges without explicit user consent. This vulnerability affects Firefox < 58.
CVE-2018-5112 2 Canonical, Mozilla 2 Ubuntu Linux, Firefox 2019-10-02 5.0 MEDIUM 7.5 HIGH
Development Tools panels of an extension are required to load URLs for the panels as relative URLs from the extension manifest file but this requirement was not enforced in all instances. This could allow the development tools panel for the extension to load a URL that it should not be able to access, including potentially privileged pages. This vulnerability affects Firefox < 58.
CVE-2019-7308 3 Canonical, Linux, Opensuse 3 Ubuntu Linux, Linux Kernel, Leap 2019-09-24 4.7 MEDIUM 5.6 MEDIUM
kernel/bpf/verifier.c in the Linux kernel before 4.20.6 performs undesirable out-of-bounds speculation on pointer arithmetic in various cases, including cases of different branches with different state or limits to sanitize, leading to side-channel attacks.
CVE-2011-2767 4 Apache, Canonical, Debian and 1 more 7 Mod Perl, Ubuntu Linux, Debian Linux and 4 more 2019-09-24 10.0 HIGH 9.8 CRITICAL
mod_perl 2.0 through 2.0.10 allows attackers to execute arbitrary Perl code by placing it in a user-owned .htaccess file, because (contrary to the documentation) there is no configuration option that permits Perl code for the administrator's control of HTTP request processing without also permitting unprivileged users to run Perl code in the context of the user account that runs Apache HTTP Server processes.
CVE-2019-15717 2 Canonical, Irssi 2 Ubuntu Linux, Irssi 2019-09-14 7.5 HIGH 9.8 CRITICAL
Irssi 1.2.x before 1.2.2 has a use-after-free if the IRC server sends a double CAP.
