libpango in Pango 1.40.8 through 1.42.3, as used in hexchat and other products, allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via crafted text with invalid Unicode sequences.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
