CVE-2016-10739

CVE-2016-10739 affects glibc (getaddrinfo) up to version 2.28, where a string containing an IPv4 address followed by whitespace and extra characters could be misinterpreted as valid. This may allow an attacker to bypass validation or embed dangerous substrings in inputs that appear to be legitima...

Design/Logic Flaw

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

Summary: CVE-2018-19591 affects the GNU C Library (glibc/libc6). In versions up to 2.28, getaddrinfo() may allocate a socket descriptor for a crafted hostname that is not closed, related to if_nametoindex(). The issue is documented across multiple sources (CVE entry and downstream advisories). Af...

Medium: glibc

Issue Overview: stdlib/canonicalize.c in the GNU C Library aka glibc or libc6 2.27 and earlier, when processing very long pathname arguments to the realpath function, could encounter an integer overflow on 32-bit architectures, leading to a stack-based buffer overflow and, potentially, arbitrary...

CVE-2018-11237

An AVX-512-optimized implementation of the mempcpy function in the GNU C Library aka glibc or libc6 2.27 and earlier may write data beyond the target buffer, leading to a buffer overflow in mempcpyavx512novzeroupper...

CVE-2018-11236

Summary (CVE-2018-11236) : In glibc, the realpath path processing path can trigger an integer overflow in 32-bit builds within stdlib/canonicalize.c when handling very long pathname arguments, producing a stack-based buffer overflow and potentially arbitrary code execution. The vulnerability affe...

CVE-2017-18269

CVE-2017-18269 affects glibc (memcpy-sse2-unaligned on i386) where the overlapping memory check can fail when the source spans the middle of the address space, producing data corruption that may lead to information disclosure, DoS, or potentially code execution. Affected versions: glibc 2.21–2.27...

CVE-2018-11237

CVE-2018-11237: A buffer overflow in the AVX-512-optimized mempcpy implementation (__mempcpy_avx512_no_vzeroupper) of glibc (2.27 and earlier). The overflow occurs when copying data beyond the target buffer, as demonstrated by vulnerable mempcpy paths described in public advisories and exploits. ...

Design/Logic Flaw

The malloc implementation in the GNU C Library aka glibc or libc6, from version 2.24 to 2.26 on powerpc, and only in version 2.26 on i386, did not properly handle malloc calls with arguments close to SIZEMAX and could return a pointer to a heap region that is smaller than requested, eventually...

CVE-2018-6551

CVE-2018-6551 concerns the GNU C Library (glibc) malloc implementation with arguments near SIZE_MAX, causing heap corruption due to an integer overflow. Affected are glibc versions 2.24–2.26 on powerpc and 2.26 on i386. IBM advisories (IMM2, DSA Preboot, AMM) reference CVE-2018-6551 and describe ...

CVE-2018-6485

CVE-2018-6485 is an integer overflow in posix_memalign within glibc (memalign implementation) for versions 2.26 and earlier, which could cause a heap area to be too small and lead to heap corruption. The NVD CVSSv3/base score is 9.8 (CRITICAL) with network attack vector, no user interaction. Affe...

Updated glibc packages fix security vulnerabilities

The DNS stub resolver in the GNU C Library aka glibc or libc6 before version 2.26, when EDNS support is enabled, will solicit large UDP responses from name servers, potentially simplifying off-path DNS spoofing attacks due to IP fragmentation.CVE-2017-12132, CVE-2017-12133. The GNU C Library aka...

CVE-2017-17426

CVE-2017-17426 affects the GNU C Library (glibc/libc6) up to version 2.26. The heap overflow arises from an integer overflow check missing in the per-thread cache (tcache) path when allocating an object near SIZE_MAX, potentially allowing code execution. Exploitation details are not provided in t...

CVE-2017-15804

CVE-2017-15804 affects the GNU C Library (glibc) glob() implementation: a buffer overflow occurs during unescaping of user names with the ~ operator in glob.c, in glibc versions before 2.27. Multiple connected advisories (e.g., ALAS2-2018-1048, CESA/CentOS notes) confirm the issue and list glibc ...
