CVE-1999-0199

manual/search.texi in the GNU C Library aka glibc before 2.2 lacks a statement about the unspecified tdelete return value upon deletion of a tree's root, which might allow attackers to access a dangling pointer in an application whose developer was unaware of a documentation update from 1999...

RHEL 7 : glibc (RHSA-2020:3861)

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2020:3861 advisory. The glibc packages provide the standard C libraries libc, POSIX thread libraries libpthread, standard math libraries libm, and the name service cache...

glibc: LD_PREFER_MAP_32BIT_EXEC not ignored in setuid binaries

A vulnerability was discovered in glibc where the LDPREFERMAP32BITEXEC environment variable is not ignored when running binaries with the setuid flag on x8664 architectures. This allows an attacker to force system to utilize only half of the memory making the system think the software is 32-bit...

EulerOS 2.0 SP3 : glibc (EulerOS-SA-2020-2131)

According to the versions of the glibc packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - The GNU C Library aka glibc or libc6 before 2.32 could overflow an on-stack buffer during range reduction if an input to an 80-bit long double...

On the x86-64 architecture the GNU C Library (aka glibc) before 2.31 fails to ignore the LD_PREFER_MAP_32BIT_EXEC environment variable during program execution after a security transition allowing local attackers to restrict the possible mapping addresses for loaded libraries and thus bypass ASLR for a setuid program.

...

An out-of-bounds write vulnerability was found in glibc before 2.31 when handling signal trampolines on PowerPC. Specifically the backtrace function did not properly check the array bounds when storing the frame address resulting in a denial of service or potential code execution. The highest threat from this vulnerability is to system availability.
