golang: ReadUvarint and ReadVarint can read an unlimited number of bytes from invalid inputs

A flaw was found in the Go encoding/binary package. Certain invalid inputs to the ReadUvarint or the ReadVarint causes those functions to read an unlimited number of bytes from the ByteReader argument before returning an error. This flaw possibly leads to processing more input than expected. The...

The vulnerability of the Pillow image processing library, related to writing data beyond the buffer boundary in memory during the conversion from SGI images to RLE format, allows a hacker to trigger a service denial.

The vulnerability of the Pillow image processing library is related to the writing of data beyond the buffer boundary in memory during the conversion of SGI images to RLE format. Exploiting this vulnerability can allow a remote attacker to cause a service failure...

The vulnerability of the PCX P library for image processing in Pillow allows a hacker to trigger a service failure.

The vulnerability of the PCX P library for image processing in Pillow relates to the issue of the operation exceeding the buffer boundaries in memory during the encoding of PCX images. Exploiting this vulnerability could allow a malicious actor to cause service failures remotely...
