Constructed ASN.1 types with a recursive definition could exceed the stack

Constructed ASN.1 types with a recursive definition (such as can be found in PKCS7) could eventually exceed the stack given malicious input with excessive recursion. This could result in a Denial Of Service attack. There are no such structures used within SSL/TLS that come from untrusted sources so this is considered safe. Fixed in OpenSSL 1.1.0h (Affected 1.1.0-1.1.0g). Fixed in OpenSSL 1.0.2o (Affected 1.0.2b-1.0.2n).

mailman: Cross-site scripting vulnerability allows malicious listowners to inject scripts into listinfo pages

wget: Cookie injection allows malicious website to write arbitrary cookie entries into cookie jar

GNU Wget before 1.19.5 is prone to a cookie injection vulnerability in the resp_new function in http.c via a \r\n sequence in a continuation line.

A security vulnerability in HPE IceWall SSO Dfw 10.0 and 11.0 on RHEL, HP-UX, and Windows could be exploited remotely to allow URL Redirection.

Mozilla: RSS Feed vulnerable to new line Injection

RSS fields can inject new lines into the created email structure, modifying the message body. This vulnerability affects Thunderbird < 52.5.2.

Mozilla: Local path string can be leaked from RSS feed

Crafted CSS in an RSS feed can leak and reveal local path strings, which may contain user name. This vulnerability affects Thunderbird < 52.5.2.

Mozilla: JavaScript Execution via RSS in mailbox:// origin

It is possible to execute JavaScript in the parsed RSS feed when RSS feed is viewed as a website, e.g. via "View -> Feed article -> Website" or in the standard format of "View -> Feed article -> default format". This vulnerability affects Thunderbird < 52.5.2.

Mozilla: From address with encoded null character is cut off in message header display

It is possible to spoof the sender's email address and display an arbitrary sender address to the email recipient. The real sender's address is not displayed if preceded by a null character in the display string. This vulnerability affects Thunderbird < 52.5.2.

nss: Potential use-after-free in TLS 1.2 server when verifying client authentication

During TLS 1.2 exchanges, handshake hashes are generated which point to a message buffer. This saved data is used for later messages but in some cases, the handshake transcript can exceed the space available in the current buffer, causing the allocation of a new buffer. This leaves a pointer pointing to the old, freed buffer, resulting in a use-after-free when handshake hashes are then calculated afterwards. This can result in a potentially exploitable crash. This vulnerability affects Firefox < 56, Firefox ESR < 52.4, and Thunderbird < 52.4.

Mozilla: Same-origin policy bypass with iframes through page reloads (MFSA 2017-19)

Same-origin policy protections can be bypassed on pages with embedded iframes during page reloads, allowing the iframes to access content on the top level page, leading to information disclosure. This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55.

Mozilla: Buffer overflow while painting non-displayable SVG (MFSA 2017-19)

A buffer overflow can occur when the image renderer attempts to paint non-displayable SVG elements. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55.

Mozilla: Use-after-free with image observers (MFSA 2017-19)

A use-after-free vulnerability can occur when reading an image observer during frame reconstruction after the observer has been freed. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55.

Mozilla: address bar username and password spoofing in reader mode

When entered directly, Reader Mode did not strip the username and password section of URLs displayed in the addressbar. This can be used for spoofing the domain of the current page. This vulnerability affects Firefox < 54.

krb5: Authentication bypass by improper validation of certificate EKU and SAN

An authentication bypass flaw was found in the way krb5's certauth interface before 1.16.1 handled the validation of client certificates. A remote attacker able to communicate with the KDC could potentially use this flaw to impersonate arbitrary principals under rare and erroneous circumstances.
