Summary
ecryptfs: pass packet set buffer size to parser
Details

In the Linux kernel, the following vulnerability has been resolved:

ecryptfs: pass packet set buffer size to parser

ecryptfs_parse_packet_set() receives a pointer into the file header, but it calculates the remaining packet buffer size from PAGE_SIZE - 8. For version 1 headers the packet set starts later in the header, so this can overstate the available buffer.

Pass the actual packet set buffer length from the caller and calculate per-packet limits from the remaining bytes in that buffer. Recompute the remaining length after consuming a tag 3 packet before parsing the following tag 11 packet.
