USN-4416-1: GNU C Library vulnerabilities | Cloud Foundry
Severity Medium Vendor Canonical Ubuntu Versions Affected Canonical Ubuntu 16.04 Canonical Ubuntu 18.04 Description Florian Weimer discovered that the GNU C Library incorrectly handled certain memory operations. A remote attacker could use this issue to cause the GNU C Library to crash, resulting...
CVE-2020-24240
GNU Bison before 3.7.1 has a use-after-free in obstackfree in lib/obstack.c called from gramlex when a '\0' byte is encountered. NOTE: there is a risk only if Bison is used with untrusted input, and the observed bug happens to cause unsafe behavior with a specific compiler/architecture. The bug...
GNU Bison Post-Release Reuse Vulnerability
GNU Bison is free software for the automatic generation of syntax parser programs. A post-release reuse vulnerability exists in GNU Bison 3.7. A local attacker can cause a system crash by exploiting this vulnerability via a specially crafted input file containing NULL bytes...

A use-after-free vulnerability introduced in glibc upstream version 2.14 was found in the way the tilde expansion was carried out. Directory paths containing an initial tilde followed by a valid username were affected by this issue. A local attacker could exploit this flaw by creating a specially crafted path that when processed by the glob function would potentially lead to arbitrary code execution. This was fixed in version 2.32.
