USN-7700-1 gcc-10, gcc-11, gcc-12 vulnerability

It was discovered that the -fstack-protector hardening feature in GCC for AArch64 did not properly protect dynamically-sized local variables such as those created using C99 variable length arrays or alloca. As a result, an attacker who was able to trigger a buffer overflow in such cases could...

Denial Of Service (DOS)

Tar is vulnerable to Denial Of Service DOS. The vulnerability is caused due to a defect in a function xattrdecoder within xheader.c where sufficiently long xattr key may overflow a stack where alloca is used. An attacker can trick a user into processing a malicious archive, causing an application...

K16366: GNU C Library (glibc) vulnerability CVE-2015-1472

Security Advisory Description stdio-common/vfscanf.c has an ADDW macro that tries to determine whether to use malloc or alloca for allocations. But in the malloc case, it only allocates newsize bytes instead of the required newsize sizeof CHART. Thus the allocated buffer gets overrun in the...

SUSE CVE-2008-2664

The rbstrformat function in Ruby 1.8.4 and earlier, 1.8.5 before 1.8.5-p231, 1.8.6 before 1.8.6-p230, 1.8.7 before 1.8.7-p22, and 1.9.0 before 1.9.0-2 allows context-dependent attackers to trigger memory corruption via unspecified vectors related to alloca, a different issue than CVE-2008-2662,...

SUSE CVE-2012-3406

The vfprintf function in stdio-common/vfprintf.c in GNU C Library aka glibc 2.5, 2.12, and probably other versions does not "properly restrict the use of" the alloca function when allocating the SPECS array, which allows context-dependent attackers to bypass the FORTIFYSOURCE format-string...

SUSE CVE-2015-1473

The ADDW macro in stdio-common/vfscanf.c in the GNU C Library aka glibc or libc6 before 2.21 does not properly consider data-type size during a risk-management decision for use of the alloca function, which might allow context-dependent attackers to cause a denial of service segmentation violatio...

SUSE CVE-2018-10907

It was found that glusterfs server is vulnerable to multiple 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...
