Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2015-8776)

The vulnerability allows a remote non-authenticated attacker to read data or crash the application.

The strftime function in the GNU C Library (aka glibc or libc6) before 2.23 allows context-dependent attackers to cause a denial of service (application crash) or possibly obtain sensitive information via an out-of-range time value.


2) Security features bypass (CVE-ID: CVE-2015-8777)

The vulnerability allows a local user to manipulate data.

The process_envvars function in elf/rtld.c in the GNU C Library (aka glibc or libc6) before 2.23 allows local users to bypass a pointer-guarding protection mechanism via a zero value of the LD_POINTER_GUARD environment variable.


3) Buffer overflow (CVE-ID: CVE-2015-8778)

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

Integer overflow in the GNU C Library (aka glibc or libc6) before 2.23 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via the size argument to the __hcreate_r function, which triggers out-of-bounds heap-memory access.


4) Stack-based buffer overflow (CVE-ID: CVE-2015-8779)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when processing a long catalog name. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
