CVE-2009-3555 7 Apache, Canonical, Debian and 4 more 7 Http Server, Ubuntu Linux, Debian Linux and 4 more 2021-02-05 5.8 MEDIUM N/A
The TLS protocol, and the SSL protocol 3.0 and possibly earlier, as used in Microsoft Internet Information Services (IIS) 7.0, mod_ssl in the Apache HTTP Server 2.2.14 and earlier, OpenSSL before 0.9.8l, GnuTLS 2.8.5 and earlier, Mozilla Network Security Services (NSS) 3.12.4 and earlier, multiple Cisco products, and other products, does not properly associate renegotiation handshakes with an existing connection, which allows man-in-the-middle attackers to insert data into HTTPS sessions, and possibly other types of sessions protected by TLS or SSL, by sending an unauthenticated request that is processed retroactively by a server in a post-renegotiation context, related to a "plaintext injection" attack, aka the "Project Mogul" issue.
CVE-2020-29573 2 Gnu, Redhat 2 Glibc, Enterprise Linux 2021-01-26 5.0 MEDIUM 7.5 HIGH
sysdeps/i386/ldbl2mpn.c in the GNU C Library (aka glibc or libc6) before 2.23 on x86 targets has a stack-based buffer overflow if the input to any of the printf family of functions is an 80-bit long double with a non-canonical bit pattern, as seen when passing a \x00\x04\x00\x00\x00\x00\x00\x00\x00\x04 value to sprintf. NOTE: the issue does not affect glibc by default in 2016 or later (i.e., 2.23 or later) because of commits made in 2015 for inlining of C99 math functions through use of GCC built-ins. In other words, the reference to 2.23 is intentional despite the mention of "Fixed for glibc 2.33" in the 26649 reference.
CVE-2020-16592 1 Gnu 1 Binutils 2021-01-15 4.3 MEDIUM 5.5 MEDIUM

CVE-2020-12137 2 Debian, Gnu 2 Debian Linux, Mailman 2020-10-27 4.3 MEDIUM 6.1 MEDIUM
GNU Mailman 2.x before 2.1.30 uses the .obj extension for scrubbed application/octet-stream MIME parts. This behavior may contribute to XSS attacks against list-archive visitors, because an HTTP reply from an archive web server may lack a MIME type, and a web browser may perform MIME sniffing, conclude that the MIME type should have been text/html, and execute JavaScript code.
CVE-2020-24659 2 Fedoraproject, Gnu 2 Fedora, Gnutls 2020-10-26 5.0 MEDIUM 7.5 HIGH
An issue was discovered in GnuTLS before 3.6.15. A server can trigger a NULL pointer dereference in a TLS 1.3 client if a no_renegotiation alert is sent with unexpected timing, and then an invalid second handshake occurs. The crash happens in the application's error handling path, where the gnutls_deinit function is called after detecting a handshake failure.
CVE-2018-10846 5 Canonical, Debian, Fedoraproject and 2 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2020-10-22 1.9 LOW 5.6 MEDIUM

CVE-2017-16997 2 Gnu, Redhat 4 Glibc, Enterprise Linux Desktop, Enterprise Linux Server and 1 more 2020-10-15 9.3 HIGH 7.8 HIGH
elf/dl-load.c in the GNU C Library (aka glibc or libc6) 2.19 through 2.26 mishandles RPATH and RUNPATH containing $ORIGIN for a privileged (setuid or AT_SECURE) program, which allows local users to gain privileges via a Trojan horse library in the current working directory, related to the fillin_rpath and decompose_rpath functions. This is associated with misinterpretion of an empty RPATH/RUNPATH token as the "./" directory. NOTE: this configuration of RPATH/RUNPATH for a privileged program is apparently very uncommon; most likely, no such program is shipped with any common Linux distribution.
CVE-2017-1000366 8 Debian, Gnu, Mcafee and 5 more 20 Debian Linux, Glibc, Web Gateway and 17 more 2020-10-15 7.2 HIGH 7.8 HIGH
glibc contains a vulnerability that allows specially crafted LD_LIBRARY_PATH values to manipulate the heap/stack, causing them to alias, potentially resulting in arbitrary code execution. Please note that additional hardening changes have been made to glibc to prevent manipulation of stack and heap memory but these issues are not directly exploitable, as such they have not been given a CVE. This affects glibc 2.25 and earlier.
CVE-2019-15847 2 Gnu, Opensuse 2 Gcc, Leap 2020-09-17 5.0 MEDIUM 7.5 HIGH
The POWER9 backend in GNU Compiler Collection (GCC) before version 10 could optimize multiple calls of the __builtin_darn intrinsic into a single call, thus reducing the entropy of the random number generator. This occurred because a volatile operation was not specified. For example, within a single execution of a program, the output of every __builtin_darn() call may be the same.
CVE-2016-9401 3 Debian, Gnu, Redhat 8 Debian Linux, Bash, Enterprise Linux Desktop and 5 more 2020-09-14 2.1 LOW 5.5 MEDIUM
