1 CVE-2021-27851 59 2021-04-26 2022-07-29
2.1
 None Local Low Not required None Partial None
A security vulnerability that can lead to local privilege escalation has been found in ’guix-daemon’. It affects multi-user setups in which ’guix-daemon’ runs locally. The attack consists in having an unprivileged user spawn a build process, for instance with `guix build`, that makes its build directory world-writable. The user then creates a hardlink to a root-owned file such as /etc/shadow in that build directory. If the user passed the --keep-failed option and the build eventually fails, the daemon changes ownership of the whole build tree, including the hardlink, to the user. At that point, the user has write access to the target file. Versions after and including v0.11.0-3298-g2608e40988, and versions prior to v1.2.0-75109-g94f0312546 are vulnerable.
2 CVE-2021-3981 276 2022-03-10 2022-10-28
2.1
 None Local Low Not required Partial None None
A flaw in grub2 was found where its configuration file, known as grub.cfg, is being created with the wrong permission set allowing non privileged users to read its content. This represents a low severity confidentiality issue, as those users can eventually read any encrypted passwords present in grub.cfg. This flaw affects grub2 2.06 and previous versions. This issue has been fixed in grub upstream but no version with the fix is currently released.
3 CVE-2020-29562 617 DoS 2020-12-04 2021-03-19
2.1
 None Remote High ??? None None Partial
The iconv function in the GNU C Library (aka glibc or libc6) 2.30 to 2.32, when converting UCS4 text containing an irreversible character, fails an assertion in the code path and aborts the program, potentially resulting in a denial of service.
4 CVE-2020-27618 835 DoS 2021-02-26 2022-10-28
2.1
 None Local Low Not required None None Partial
The iconv function in the GNU C Library (aka glibc or libc6) 2.32 and earlier, when processing invalid multi-byte input sequences in IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 encodings, fails to advance the input state, which could lead to an infinite loop in applications, resulting in a denial of service, a different vulnerability from CVE-2016-10228.
5 CVE-2020-23856 416 DoS 2021-05-18 2022-01-01
2.1

2.1
 None Local Low Not required None None Partial
GNU Bison before 3.5.4 allows attackers to cause a denial of service (application crash). NOTE: there is a risk only if Bison is used with untrusted input, and an observed bug happens to cause unsafe behavior with a specific compiler/architecture. The bug reports were intended to show that a crash may occur in Bison itself, not that a crash may occur in code that is generated by Bison.
8 CVE-2020-10029 787 Overflow 2020-03-04 2022-11-10
2.1
 None Local Low Not required None None Partial
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 function contains a non-canonical bit pattern, a seen when passing a 0x5d414141414141410000 value to sinl on x86 targets. This is related to sysdeps/ieee754/ldbl-96/e_rem_pio2l.c.
9 CVE-2019-19126 665 Bypass 2019-11-19 2022-11-08
2.1
 None Local Low Not required Partial None None
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.
10 CVE-2019-7309 2019-02-03 2020-08-24
2.1
 None Local Low Not required None None Partial
In the GNU C Library (aka glibc or libc6) through 2.29, the memcmp function for the x32 architecture can incorrectly return zero (indicating that the inputs are equal) because the RDX most significant bit is mishandled.
11 CVE-2018-20483 200 +Info 2018-12-26 2020-08-24
2.1
 None Local Low Not required Partial None None
set_file_metadata in xattr.c in GNU Wget before 1.20.1 stores a file's origin URL in the user.xdg.origin.url metadata attribute of the extended attributes of the downloaded file, which allows local users to obtain sensitive information (e.g., credentials contained in the URL) by reading this attribute, as demonstrated by getfattr. This also applies to Referer information in the user.xdg.referrer.url metadata attribute. According to 2016-07-22 in the Wget ChangeLog, user.xdg.origin.url was partially based on the behavior of fwrite_xattr in tool_xattr.c in curl.
12 CVE-2017-1000455 346 2018-01-02 2018-01-30
2.1
 None Local Low Not required None Partial None
GuixSD prior to Git commit 5e66574a128937e7f2fcf146d146225703ccfd5d used POSIX hard links incorrectly, leading the creation of setuid executables in "the store", violating a fundamental security assumption of GNU Guix.

This could potentially lead to less randomness in random number generation.
