Summary

eglibc, glibc vulnerabilities

Details

It was discovered that the GNU C library did not properly handle all of the possible return values from the kernel getcwd(2) syscall. A local attacker could potentially exploit this to execute arbitrary code in setuid programs and gain administrative privileges. (CVE-2018-1000001)

A memory leak was discovered in the dlinitpaths() function in the GNU C library dynamic loader. A local attacker could potentially exploit this with a specially crafted value in the LDHWCAP_MASK environment variable, in combination with CVE-2017-1000409 and another vulnerability on a system with hardlink protections disabled, in order to gain administrative privileges. (CVE-2017-1000408)

A heap-based buffer overflow was discovered in the dlinitpaths() function in the GNU C library dynamic loader. A local attacker could potentially exploit this with a specially crafted value in the LDLIBRARY_PATH environment variable, in combination with CVE-2017-1000408 and another vulnerability on a system with hardlink protections disabled, in order to gain administrative privileges. (CVE-2017-1000409)

An off-by-one error leading to a heap-based buffer overflow was discovered in the GNU C library glob() implementation. An attacker could potentially exploit this to cause a denial of service or execute arbitrary code via a maliciously crafted pattern. (CVE-2017-15670)

A heap-based buffer overflow was discovered during unescaping of user names with the ~ operator in the GNU C library glob() implementation. An attacker could potentially exploit this to cause a denial of service or execute arbitrary code via a maliciously crafted pattern. (CVE-2017-15804)

It was discovered that the GNU C library dynamic loader mishandles RPATH and RUNPATH containing $ORIGIN for privileged (setuid or AT_SECURE) programs. A local attacker could potentially exploit this by providing a specially crafted library in the current working directory in order to gain administrative privileges. (CVE-2017-16997)

It was discovered that the GNU C library malloc() implementation could return a memory block that is too small if an attempt is made to allocate an object whose size is close to SIZE_MAX, resulting in a heap-based overflow. An attacker could potentially exploit this to cause a denial of service or execute arbitrary code. This issue only affected Ubuntu 17.10. (CVE-2017-17426)
