Updated curl packages fix security vulnerability

If cookie state is written into a cookie jar file that is later read back and used for subsequent requests, a malicious HTTP server can inject new cookies for arbitrary domains into said cookie jar. The issue pertains to the function that loads cookies into memory, which reads the specified file...

CVE-2017-17426

The malloc function in the GNU C Library aka glibc or libc6 2.26 could return a memory block that is too small if an attempt is made to allocate an object whose size is close to SIZEMAX, potentially leading to a subsequent heap overflow. This occurs because the per-thread cache aka tcache feature...

GNU C Library integer overflow vulnerability (CNVD-2018-00256)

The GNU C Library a.k.a. glibc, libc6 is an open-source, free C language compiler released under the LGPL license. An integer overflow vulnerability exists in the 'malloc' function in version 2.26 of the GNU C Library, which stems from the program returning a small block of memory. No information...

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...
