Summary
linux vulnerabilities
Details

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)
