[USN-2563-1] Linux kernel vulnerabilities

Severity Medium
Affected Packages 9
CVEs 5
Info Packages Vulnerabilities

Several security issues were fixed in the kernel.

Sun Baoliang discovered a use after free flaw in the Linux kernel's SCTP
(Stream Control Transmission Protocol) subsystem during INIT collisions. A
remote attacker could exploit this flaw to cause a denial of service
(system crash) or potentially escalate their privileges on the system.
(CVE-2015-1421)

Marcelo Leitner discovered a flaw in the Linux kernel's routing of packets
to too many different dsts/too fast. A remote attacker on the same subnet can exploit this
flaw to cause a denial of service (system crash). (CVE-2015-1465)

An integer overflow was discovered in the stack randomization feature of
the Linux kernel on 64 bit platforms. A local attacker could exploit this
flaw to bypass the Address Space Layout Randomization (ASLR) protection
mechanism. (CVE-2015-1593)

An information leak was discovered in the Linux Kernel's handling of
userspace configuration of the link layer control (LLC). A local user could
exploit this flaw to read data from other sysctl settings. (CVE-2015-2041)

An information leak was discovered in how the Linux kernel handles setting
the Reliable Datagram Sockets (RDS) settings. A local user could exploit
this flaw to read data from other sysctl settings. (CVE-2015-2042)
