In TigerVNC 1.7.1 (SMsgReader.cxx SMsgReader::readClientCutText), by causing an integer overflow, an authenticated client can crash the server.

In TigerVNC 1.7.1 (SSecurityPlain.cxx SSecurityPlain::processMsg), unauthenticated users can crash the server by sending long usernames.

In TigerVNC 1.7.1 (VNCSConnectionST.cxx VNCSConnectionST::fence), an authenticated client can cause a double free, leading to denial of service or potentially code execution.

In TigerVNC 1.7.1 (SSecurityVeNCrypt.cxx SSecurityVeNCrypt::SSecurityVeNCrypt), an unauthenticated client can cause a small memory leak in the server.

A Cross-Site Scripting (XSS) was discovered in ‘Magmi 0.7.22’. The vulnerability exists due to insufficient filtration of user-supplied data (prefix) passed to the ‘magmi-git-master/magmi/web/ajax_gettime.php’ URL. An attacker could execute arbitrary HTML and script code in a browser in the context of the vulnerable website.

A Cross-Site Scripting (XSS) was discovered in ‘wallacepos v1.4.1’. The vulnerability exists due to insufficient filtration of user-supplied data (token) passed to the ‘wallacepos-master/myaccount/resetpassword.php’ URL. An attacker could execute arbitrary HTML and script code in a browser in the context of the vulnerable website.

Multiple Cross-Site Scripting (XSS) were discovered in ‘openeclass Release_3.5.4’. The vulnerabilities exist due to insufficient filtration of user-supplied data (meeting_id, user) passed to the ‘openeclass-master/modules/tc/webconf/webconf.php’ URL. An attacker could execute arbitrary HTML and script code in a browser in the context of the vulnerable website.

In TigerVNC 1.7.1 (CConnection.cxx CConnection::CConnection), an unauthenticated client can cause a small memory leak in the server.

A Cross-Site Scripting (XSS) was discovered in ‘SocialNetwork v1.2.1’. The vulnerability exists due to insufficient filtration of user-supplied data (mail) passed to the ‘SocialNetwork-andrea/app/template/pw_forgot.php’ URL. An attacker could execute arbitrary HTML and script code in a browser in the context of the vulnerable website.

Use-after-free vulnerability in fs/crypto/ in the Linux kernel before 4.10.7 allows local users to cause a denial of service (NULL pointer dereference) or possibly gain privileges by revoking keyring keys being used for ext4, f2fs, or ubifs encryption, causing cryptographic transform objects to be freed prematurely.
