Ubuntu 20.04: UBUNTU-2023-1542 Medium Severity: SMB Relay Vulnerability

The kernel package contains the Linux kernel (vmlinuz), the core of any

Linux operating system. The kernel handles the basic functions

of the operating system: memory allocation, process allocation, device

input and output, etc.

Updated to upstream linux kernel 2.6.20.6:

CVE-2007-1357:

The atalk_sum_skb function in AppleTalk for Linux kernel

2.6.x before 2.6.21, and possibly 2.4.x, allows remote

attackers to cause a denial of service (crash) via an

AppleTalk frame that is shorter than the specified length,

which triggers a BUG_ON call when an attempt is made to

perform a checksum.

CVSS Severity: 3.3 (Low)

Plus additional fixes:

Bugfix for ATI SB600 SATA

Routing bugfix

Libata LBA48 bugfix

Update libata NCQ blacklist

Libata request sense bugfix

SCSI error handler fix

- 2.6.20.5

- 2.6.20.6

- GFS2 update (1414)

- additional bugfixes (1820-1828)

* Wed Apr 4 2007 Markus Armbruster

- Xen kernel profiling fix is broken, back it out.

* Tue Apr 3 2007 Chuck Ebbert 1.2942

- 2.6.20.5-rc1 plus two fixes for broken -rc1 patches.

- Remove patches that are now in 20.5-rc1.

- 2106: move firmware timeout patch to here.

- 2107: Disable PCI MSI and MMCONFIG by default,

add options to enable them.
