CVE-2015-8778
CriticalSummary
Integer overflow in the GNU C Library (glibc or libc6) before version 2.23 allows context-dependent attackers to cause application crashes or potentially execute arbitrary code via the size argument to the __hcreate_r function, leading to out-of-bounds heap-memory access.
Risk Assessment
Organizations may experience application crashes, leading to service downtime. There is also a risk of arbitrary code execution, which could result in serious security breaches.
Recommendation
It is recommended to update the glibc library to version 2.23 or later to mitigate this vulnerability. Additionally, monitor applications using this library for unauthorized access.
Other vulnerabilities in GNU C Library (glibc or libc6)
See all- CVE-2015-8982High
Integer overflow in the strxfrm function in the GNU C Library (glibc or libc6) before version 2.21 allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long string, leading to a stack-based buffer overflow.
- CVE-2015-1472High
The ADDW macro in stdio-common/vfscanf.c in the GNU C Library (glibc or libc6) before version 2.21 does not properly consider data-type size during memory allocation, which may lead to buffer overflow or other unspecified impacts.
- CVE-2014-9984Critical
nscd in the GNU C Library (glibc or libc6) before version 2.20 does not correctly compute the size of an internal buffer when processing netgroup requests, possibly leading to an nscd daemon crash or code execution as the user running nscd.
Original NVD description (English source)
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.
