CVE-2019-6488

CVE-2019-6488 affects the GNU C Library (glibc) on x32, where the assembly path for size_t incorrectly uses a 64-bit register. This discrepancy can cause a crash in __memmove_avx_unaligned_erms during memcpy, leading to a segmentation fault or potentially other impact as described in the vulnerab...

CVE-2019-6488

The string component in the GNU C Library aka glibc or libc6 through 2.28, when running on the x32 architecture, incorrectly attempts to use a 64-bit register for sizet in assembly codes, which can lead to a segmentation fault or possibly unspecified other impact, as demonstrated by a crash in...

[SECURITY] Fedora 29 Update: kernel-headers-4.19.15-300.fc29

Kernel-headers includes the C header files that specify the interface between the Linux kernel and userspace libraries and programs. The header files define structures and constants that are needed for building most standard programs and are also needed for rebuilding the glibc package...

[SECURITY] Fedora 28 Update: kernel-headers-4.19.15-200.fc28

Kernel-headers includes the C header files that specify the interface between the Linux kernel and userspace libraries and programs. The header files define structures and constants that are needed for building most standard programs and are also needed for rebuilding the glibc package...

Privilege Escalation

glibc is vulnerable to privilege escalation attacks. The vulnerability exists as elf/dl-load.c in the GNU C Library aka glibc or libc6 2.19 through 2.26 mishandles RPATH and RUNPATH containing $ORIGIN for a privileged setuid or ATSECURE program, which allows local users to gain privileges via a...

Arbitrary Code Execution

glibc is vulnerable to arbitrary code execution. A buffer overflow vulnerability in the glob function in glob.c, caused by an off-by-one error, allows an attacker to execute arbitrary code and escalate his privileges...

Arbitrary Code Execution

glibc is vulnerable to arbitrary code execution. A flaw was found in the way memory was being allocated on the stack for user space binaries. If heap or different memory region and stack memory regions were adjacent to each other, an attacker could use this flaw to jump over the stack guard gap,...

Denial Of Service (DoS)

glibc is vulnerable to denial of service. A stack overflow vulnerability was found in nan functions that could cause applications, which process long strings with the nan function, to crash or, potentially, execute arbitrary code...

Denial Of Service (DoS)

glibc is vulnerable to denial of service. An invalid free flaw was found in glibc's getaddrinfo function when used with the AIIDN flag. A remote attacker able to make an application call this function could use this flaw to execute arbitrary code with the permissions of the user running the...

Arbitrary Code Execution

glibc is vulnerable to arbitrary code execution attacks. The vulnerability exists as a heap-based buffer overflow in the nsshostnamedigitsdots function in glibc 2.2, and other 2.x versions before 2.18, allows context-dependent attackers to execute arbitrary code via vectors related to the 1...

Denial Of Service (DoS)

glibc is vulnerable to denial of service DoS attacks. The vulnerability exists as multiple integer overflows in malloc/malloc.c in the GNU C Library aka glibc or libc6 2.18 and earlier allow context-dependent attackers to cause a denial of service heap corruption via a large value to the 1 pvallo...

Denial Of Service (DoS)

glibc is vulnerable to denial of service DoS attacks. The vulnerability exists as an off-by-one error in the gconvtranslitfind function in gconvtrans.c in GNU C Library aka glibc allows context-dependent attackers to cause a denial of service crash or execute arbitrary code via vectors related to...

Directory Traversal

glibc is vulnerable to directory traversal attacks. The vulnerability exists through multiple directory traversal vulnerabilities in GNU C Library aka glibc or libc6 before 2.20 allow context-dependent attackers to bypass ForceCommand restrictions and possibly have other unspecified impact via a...

Remote Code Execution (RCE)

glibc is vulnerable to remote code execution RCE attacks. The vulnerability exists through multiple integer overflows in the 1 strtod, 2 strtof, 3 strtold, 4 strtodl, and other unspecified "related functions" in stdlib in GNU C Library aka glibc or libc6 2.16 allow local users to cause a denial o...

Remote Code Execution (RCE)

glibc is vulnerable to remote code execution RCE attacks. The vulnerability exists as 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, whi...

Denial Of Service (DoS)

glibc is vulnerable to denial of service DoS attacks. The vulnerability exists through a buffer overflow issue in the extendbuffers function in the regular expression matcher posix/regexec.c in glibc, possibly 2.17 and earlier, allows context-dependent attackers to cause a denial of service memor...

Amazon Linux 2 : glibc (ALAS-2019-1140)

In the GNU C Library aka glibc or libc6 through 2.28, attempting to resolve a crafted hostname via getaddrinfo leads to the allocation of a socket descriptor that is not closed. This is related to the ifnametoindex function.CVE-2018-19591 C Tenable Network Security, Inc. The descriptive text and...

PHP 5.6.x < 5.6.6 Multiple Vulnerabilities (GHOST)

According to its banner, the version of PHP 5.6.x installed on the remote host is prior to 5.6.6. It is, therefore, affected by multiple vulnerabilities : - A heap-based buffer overflow flaw in the GNU C Library glibc due to improperly validating user-supplied input in the glibc functions...
