Title
USN-2637-1 -- Linux kernel vulnerabilities
Description
Xiong Zhou discovered a bug in the way the EXT4 filesystem handles
fallocate zero range functionality when the page size is greater than the
block size. A local attacker could exploit this flaw to cause a denial of
service (system crash). (CVE-2015-0275)
Wen Xu discovered a use-after-free flaw in the Linux kernel's ipv4 ping
support. A local user could exploit this flaw to cause a denial of service
(system crash) or gain administrative privileges on the system.

Comment
: The ext4_zero_range function in fs/ext4/extents.c in the Linux kernel before 4.1 allows local users to cause a denial of service (BUG) via a crafted fallocate zero-range request.

Comment
: The ping_unhash function in net/ipv4/ping.c in the Linux kernel before 4.0.3 does not initialize a certain list data structure during an unhash operation, which allows local users to gain privileges or cause a denial of service (use-after-free and system crash) by leveraging the ability to make a SOCK_DGRAM socket system call for the IPPROTO_ICMP or IPPROTO_ICMPV6 protocol, and then making a connect system call after a disconnect.
