- CVEs with nessus.description==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 _dl_init_paths() function in the GNU C library dynamic loader. A local attacker could potentially exploit this with a specially crafted value in the LD_HWCAP_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 _dl_init_paths() function in the GNU C library dynamic loader. A local attacker could potentially exploit this with a specially crafted value in the LD_LIBRARY_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).
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
