| CVE-2016-2781 | coreutils | 8.28-1ubuntu1 | chroot in GNU coreutils, when used with --userspec, allows local users to escape to the parent session via a crafted TIOCSTI ioctl call, which pushes characters to the terminal's input buffer. |
| CVE-2018-14048 | libpng1.6 | 1.6.34-1ubuntu0.18.04.2 | An issue has been found in libpng 1.6.34. It is a SEGV in the function png_free_data in png.c, related to the recommended error handling for png_read_image. |
| CVE-2018-5710 | krb5 | 1.16-2ubuntu0.2 | An issue was discovered in MIT Kerberos 5 (aka krb5) through 1.16. The pre-defined function "strlen" is getting a "NULL" string as a parameter value in plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c in the Key Distribution Center (KDC), which allows remote authenticated users to cause a denial of service (NULL pointer dereference) via a modified kadmin client. |
| CVE-2020-25697 | libx11 | 2:1.6.4-3ubuntu0.4 | A privilege escalation flaw was found due to lack of authentication for X11 clients. An attacker could use this flaw to take control of an X application by impersonating the server it is expecting to connect to. |
| CVE-2016-10739 | glibc | 2.27-3ubuntu1.5 | In the GNU C Library (aka glibc or libc6) through 2.28, the getaddrinfo function would successfully parse a string that contained an IPv4 address followed by whitespace and arbitrary characters, which could lead applications to incorrectly assume that it had parsed a valid string, without the possibility of embedded HTTP headers or other potentially dangerous substrings. |
| CVE-2021-33574 | glibc | 2.27-3ubuntu1.5 | The mq_notify function in the GNU C Library (aka glibc) versions 2.32 and 2.33 has a use-after-free. It may use the notification thread attributes object (passed through its struct sigevent parameter) after it has been freed by the caller, leading to a denial of service (application crash) or possibly unspecified other impact. |
| CVE-2015-20107 | python2.7 | 2.7.17-1~18.04ubuntu1.7 | In Python (aka CPython) through 3.10.4, the mailcap module does not add escape characters into commands discovered in the system mailcap file. This may allow attackers to inject shell commands into applications that call mailcap.findmatch with untrusted input (if they lack validation of user-provided filenames or arguments). |
| CVE-2019-13050 | gnupg2 | 2.2.4-1ubuntu1.4 | Interaction between the sks-keyserver code through 1.2.0 of the SKS keyserver network, and GnuPG through 2.2.16, makes it risky to have a GnuPG keyserver configuration line referring to a host on the SKS keyserver network. Retrieving data from this network may cause a persistent denial of service, because of a Certificate Spamming Attack. |
| CVE-2020-9849 | sqlite3 | 3.22.0-1ubuntu0.4 | An information disclosure issue was addressed with improved state management. This issue is fixed in macOS Big Sur 11.0.1, watchOS 7.0, iOS 14.0 and iPadOS 14.0, iTunes for Windows 12.10.9, iCloud for Windows 11.5, tvOS 14.0. A remote attacker may be able to leak memory. |
| CVE-2020-9991 | sqlite3 | 3.22.0-1ubuntu0.4 | This issue was addressed with improved checks. This issue is fixed in macOS Big Sur 11.0.1, watchOS 7.0, iOS 14.0 and iPadOS 14.0, iCloud for Windows 7.21, tvOS 14.0. A remote attacker may be able to cause a denial of service. |
| CVE-2018-16868 | gnutls28 | 3.5.18-1ubuntu1.5 | A Bleichenbacher type side-channel based padding oracle attack was found in the way gnutls handles verification of RSA decrypted PKCS#1 v1.5 data. An attacker who is able to run process on the same physical core as the victim process, could use this to extract plaintext or in some cases downgrade any TLS connections to a vulnerable server. |
| CVE-2019-12098 | heimdal | 7.5.0+dfsg-1 | In the client side of Heimdal before 7.6.0, failure to verify anonymous PKINIT PA-PKINIT-KX key exchange permits a man-in-the-middle attack. This issue is in krb5_init_creds_step in lib/krb5/init_creds_pw.c. |
| CVE-2021-3671 | heimdal | 7.5.0+dfsg-1 | A null pointer de-reference was found in the way samba kerberos server handled missing sname in TGS-REQ (Ticket Granting Server - Request). An authenticated user could use this flaw to crash the samba server. |
| CVE-2017-13716 | binutils | 2.30-21ubuntu1~18.04.7 | The C++ symbol demangler routine in cplus-dem.c in libiberty, as distributed in GNU Binutils 2.29, allows remote attackers to cause a denial of service (excessive memory allocation and application crash) via a crafted file, as demonstrated by a call from the Binary File Descriptor (BFD) library (aka libbfd). |
| CVE-2019-1010204 | binutils | 2.30-21ubuntu1~18.04.7 | GNU binutils gold gold v1.11-v1.16 (GNU binutils v2.21-v2.31.1) is affected by: Improper Input Validation, Signed/Unsigned Comparison, Out-of-bounds Read. The impact is: Denial of service. The component is: gold/fileread.cc:497, elfcpp/elfcpp_file.h:644. The attack vector is: An ELF file with an invalid e_shoff header field must be opened. |
| CVE-2018-20673 | binutils | 2.30-21ubuntu1~18.04.7 | The demangle_template function in cplus-dem.c in GNU libiberty, as distributed in GNU Binutils 2.31.1, contains an integer overflow vulnerability (for "Create an array for saving the template argument values") that can trigger a heap-based buffer overflow, as demonstrated by nm. |
| CVE-2021-36084 | libsepol | 2.7-1 | The CIL compiler in SELinux 3.2 has a use-after-free in __cil_verify_classperms (called from __cil_verify_classpermission and __cil_pre_verify_helper). |
| CVE-2021-36087 | libsepol | 2.7-1 | The CIL compiler in SELinux 3.2 has a heap-based buffer over-read in ebitmap_match_any (called indirectly from cil_check_neverallow). This occurs because there is sometimes a lack of checks for invalid statements in an optional block. |
| CVE-2021-36086 | libsepol | 2.7-1 | The CIL compiler in SELinux 3.2 has a use-after-free in cil_reset_classpermission (called from cil_reset_classperms_set and cil_reset_classperms_list). |
| CVE-2021-36085 | libsepol | 2.7-1 | The CIL compiler in SELinux 3.2 has a use-after-free in __cil_verify_classperms (called from __verify_map_perm_classperms and hashtab_map). |
| CVE-2020-13776 | systemd | 237-3ubuntu10.53 | systemd through v245 mishandles numerical usernames such as ones composed of decimal digits or 0x followed by hex digits, as demonstrated by use of root privileges when privileges of the 0x0 user account were intended. NOTE: this issue exists because of an incomplete fix for CVE-2017-1000082. |
| CVE-2019-18276 | bash | 4.4.18-2ubuntu1.2 | An issue was discovered in disable_priv_mode in shell.c in GNU Bash through 5.0 patch 11. By default, if Bash is run with its effective UID not equal to its real UID, it will drop privileges by setting its effective UID to its real UID. However, it does so incorrectly. On Linux and other systems that support "saved UID" functionality, the saved UID is not dropped. An attacker with command execution in the shell can use "enable -f" for runtime loading of a new builtin, which can be a shared object that calls setuid() and therefore regains privileges. However, binaries running with an effective UID of 0 are unaffected. |
| CVE-2019-20838 | pcre3 | 2:8.39-9 | libpcre in PCRE before 8.43 allows a subject buffer over-read in JIT when UTF is disabled, and \X or \R has more than one fixed quantifier, a related issue to CVE-2019-20454. |
| CVE-2013-4235 | shadow | 1:4.5-1ubuntu2.2 | shadow: TOCTOU (time-of-check time-of-use) race condition when copying and removing directory trees |
| CVE-2018-10906 | fuse | 2.9.7-1ubuntu1 | In fuse before versions 2.9.8 and 3.x before 3.2.5, fusermount is vulnerable to a restriction bypass when SELinux is active. This allows non-root users to mount a FUSE file system with the 'allow_other' mount option regardless of whether 'user_allow_other' is set in the fuse configuration. An attacker may use this flaw to mount a FUSE file system, accessible by other users, and trick them into accessing files on that file system, possibly causing Denial of Service or other unspecified effects. |
| CVE-2012-1093 | xorg | 1:7.7+19ubuntu7.1 | The init script in the Debian x11-common package before 1:7.6+12 is vulnerable to a symlink attack that can lead to a privilege escalation during package installation. |
