| CVE-2010-0928 | openssl | 1.1.1n-0+deb11u5 | OpenSSL 0.9.8i on the Gaisler Research LEON3 SoC on the Xilinx Virtex-II Pro FPGA uses a Fixed Width Exponentiation (FWE) algorithm for certain signature calculations, and does not verify the signature before providing it to a caller, which makes it easier for physically proximate attackers to determine the private key via a modified supply voltage for the microprocessor, related to a "fault-based attack." |
| CVE-2022-0563 | util-linux | 2.36.1-8+deb11u1 | A flaw was found in the util-linux chfn and chsh utilities when compiled with Readline support. The Readline library uses an "INPUTRC" environment variable to get a path to the library config file. When the library cannot parse the specified file, it prints an error message containing data from the file. This flaw allows an unprivileged user to read root-owned files, potentially leading to privilege escalation. This flaw affects util-linux versions prior to 2.37.4. |
| CVE-2017-18018 | coreutils | 8.32-4 | In GNU Coreutils through 8.29, chown-core.c in chown and chgrp does not prevent replacement of a plain file with a symlink during use of the POSIX "-R -L" options, which allows local users to modify the ownership of arbitrary files by leveraging a race condition. |
| CVE-2017-7246 | pcre3 | 2:8.39-13 | Stack-based buffer overflow in the pcre32_copy_substring function in pcre_get.c in libpcre1 in PCRE 8.40 allows remote attackers to cause a denial of service (WRITE of size 268) or possibly have unspecified other impact via a crafted file. |
| CVE-2017-11164 | pcre3 | 2:8.39-13 | In PCRE 8.41, the OP_KETRMAX feature in the match function in pcre_exec.c allows stack exhaustion (uncontrolled recursion) when processing a crafted regular expression. |
| CVE-2017-16231 | pcre3 | 2:8.39-13 | ** DISPUTED ** In PCRE 8.41, after compiling, a pcretest load test PoC produces a crash overflow in the function match() in pcre_exec.c because of a self-recursive call. NOTE: third parties dispute the relevance of this report, noting that there are options that can be used to limit the amount of stack that is used. |
| CVE-2019-20838 | pcre3 | 2:8.39-13 | 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-2017-7245 | pcre3 | 2:8.39-13 | Stack-based buffer overflow in the pcre32_copy_substring function in pcre_get.c in libpcre1 in PCRE 8.40 allows remote attackers to cause a denial of service (WRITE of size 4) or possibly have unspecified other impact via a crafted file. |
| CVE-2019-19882 | shadow | 1:4.8.1-1 | shadow 4.8, in certain circumstances affecting at least Gentoo, Arch Linux, and Void Linux, allows local users to obtain root access because setuid programs are misconfigured. Specifically, this affects shadow 4.8 when compiled using --with-libpam but without explicitly passing --disable-account-tools-setuid, and without a PAM configuration suitable for use with setuid account management tools. This combination leads to account management tools (groupadd, groupdel, groupmod, useradd, userdel, usermod) that can easily be used by unprivileged local users to escalate privileges to root in multiple ways. This issue became much more relevant in approximately December 2019 when an unrelated bug was fixed (i.e., the chmod calls to suidusbins were fixed in the upstream Makefile which is now included in the release version 4.8). |
| CVE-2013-4235 | shadow | 1:4.8.1-1 | shadow: TOCTOU (time-of-check time-of-use) race condition when copying and removing directory trees |
| CVE-2007-5686 | shadow | 1:4.8.1-1 | initscripts in rPath Linux 1 sets insecure permissions for the /var/log/btmp file, which allows local users to obtain sensitive information regarding authentication attempts. NOTE: because sshd detects the insecure permissions and does not log certain events, this also prevents sshd from logging failed authentication attempts by remote attackers. |
| CVE-2011-4116 | perl | 5.32.1-4+deb11u2 | _is_safe in the File::Temp module for Perl does not properly handle symlinks. |
| CVE-2023-31486 | perl | 5.32.1-4+deb11u2 | HTTP::Tiny before 0.083, a Perl core module since 5.13.9 and available standalone on CPAN, has an insecure default TLS configuration where users must opt in to verify certificates. |
| CVE-2022-4899 | libzstd | 1.4.8+dfsg-2.1 | A vulnerability was found in zstd v1.4.10, where an attacker can supply empty string as an argument to the command line tool to cause buffer overrun. |
| CVE-2022-3715 | bash | 5.1-2+deb11u1 | A flaw was found in the bash package, where a heap-buffer overflow can occur in valid parameter_transform. This issue may lead to memory problems. |
