Arbitrary Code Execution

glibc is vulnerable to arbitrary code execution. It was discovered that the glibc fnmatch function did not properly restrict the use of alloca. If the function was called on sufficiently large inputs, it could cause an application using fnmatch to crash or, possibly, execute arbitrary code with t...

Denial Of Service (DoS)

The coreutils package contains the core GNU utilities. It is a combination of the old GNU fileutils, sh-utils, and textutils packages. It was discovered that the sort, uniq, and join utilities did not properly restrict the use of the alloca function. An attacker could use this flaw to crash those...

glusterfs: Stack-based buffer overflow in server-rpc-fops.c allows remote attackers to execute arbitrary code

It was found that glusterfs server is vulnerable to mulitple stack based buffer overflows due to functions in server-rpc-fopc.c allocating fixed size buffers using 'alloca3'. An authenticated attacker could exploit this by mounting a gluster volume and sending a string longer that the fixed buffe...

The vulnerability of the GNU Core Utilities system utilities allows a perpetrator to trigger a service failure.

The vulnerability of the sort utility within the GNU Core Utilities suite exists due to insufficient validation of input data. Exploiting this vulnerability allows an attacker to cause a service failure by entering a long string as an argument for the sort function when using additional parameter...

Debian DLA-350-1 : eglibc security update

The strxfrm function is vulnerable to integer overflows when computing memory allocation sizes similar to CVE-2012-4412. Furthermore since it fallbacks to use alloca when malloc fails, it is vulnerable to stack-based buffer overflows similar to CVE-2012-4424. Those issues have been fixed in Debia...
