openssl: Heap Use-After-Free in OpenSSL PKCS7_verify()

A flaw was found in OpenSSL. When processing a specially crafted PKCS7 or S/MIME Secure/Multipurpose Internet Mail Extensions signed message, a heap use-after-free vulnerability in the PKCS7verify function can be triggered. This occurs if the SignedData digestAlgorithms field is present as an emp...

copyparty renders unsanitized filenames as HTML when user uploads empty files

SummaryA DOM-Based XSS was discovered in copyparty, a portable fileserver. The vulnerability is considered low-risk. DetailsBy handing someone a maliciously-named file, and then tricking them into dragging the file into copyparty's Web-UI, an attacker could execute arbitrary javascript with the...
