Name of the Vulnerable Software and Affected Versions GNU C Library aka glibc or libc6 versions prior to 2.23 Description The issue is a stack-based buffer overflow in the GNU C Library, which occurs when the input to any of the printf family of functions is an 80-bit long double with a...

CVE-2015-7547

Multiple stack-based buffer overflows in the 1 senddg and 2 sendvc functions in the libresolv library in the GNU C Library aka glibc or libc6 before 2.23 allow remote attackers to cause a denial of service crash or possibly execute arbitrary code via a crafted DNS response that triggers a call to...

Null pointer dereference

The processenvvars 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 LDPOINTERGUARD environment variable...

CVE-2015-8777

CVE-2015-8777 is a local, environment-variable–driven bypass of the glibc pointer-guarding mechanism. The flaw exists in the GNU C Library (glibc) prior to version 2.23, where the LD_POINTER_GUARD environment variable was not ignored for privileged executions, allowing a local attacker to bypass ...

CVE-2015-8777: Undefined Security Weakness

The processenvvars 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 LDPOINTERGUARD environment variable...

CVE-2015-8982

Integer overflow in the strxfrm function in the GNU C Library aka glibc or libc6 before 2.21 allows context-dependent attackers to cause a denial of service crash or possibly execute arbitrary code via a long string, which triggers a stack-based buffer overflow...

CVE-2015-5277

The getcontents function in nssfiles/files-XXX.c in the Name Service Switch NSS in GNU C Library aka glibc or libc6 before 2.20 might allow local users to cause a denial of service heap corruption or gain privileges via a long line in the NSS files database...

CVE-2015-5277

CVE-2015-5277 affects the GNU C Library (glibc) NSS get_contents backend in nss_files, where a long line in the NSS files database can trigger heap corruption and enable local privilege escalation. Engines in connected advisories confirm this vulnerability existed in glibc prior to version 2.20 a...

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...

CVE-2015-1781

Buffer overflow in the gethostbynamer and other unspecified NSS functions in the GNU C Library aka glibc or libc6 before 2.22 allows context-dependent attackers to cause a denial of service crash or execute arbitrary code via a crafted DNS response, which triggers a call with a misaligned buffer...

CVE-2015-1781: Improper Restriction of Operations within the Bounds of a Memory Buffer

Buffer overflow in the gethostbynamer and other unspecified NSS functions in the GNU C Library aka glibc or libc6 before 2.22 allows context-dependent attackers to cause a denial of service crash or execute arbitrary code via a crafted DNS response, which triggers a call with a misaligned buffer...

Debian GNU/Linux Data Compromise

The multiple vulnerabilities in the libc6-sparcv9 package of the Debian GNU/Linux operating system may lead to breaches of confidentiality, integrity, and accessibility of protected information. These vulnerabilities can be exploited remotely...

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...

CVE-2015-1472

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 memory allocation, which allows context-dependent attackers to cause a denial of service buffer overflow or possibly have unspecified other impact via a lo...

CVE-2015-1472

CVE-2015-1472 affects the GNU C Library (glibc) prior to 2.21. The ADDW macro in stdio-common/vfscanf.c can miscalculate allocation size, leading to buffer overflows in wide-character handling during wscanf, enabling context-dependent denial of service and potentially other impact. Affected compo...
