CVE-2021-27023 2 Fedoraproject, Puppet 4 Fedora, Puppet Agent, Puppet Enterprise and 1 more 2023-11-07 5.0 MEDIUM 9.8 CRITICAL
A flaw was discovered in Puppet Agent and Puppet Server that may result in a leak of HTTP credentials when following HTTP redirects to a different host. This is similar to CVE-2018-1000007
CVE-2021-26937 3 Debian, Fedoraproject, Gnu 3 Debian Linux, Fedora, Screen 2023-11-07 7.5 HIGH 9.8 CRITICAL
encoding.c in GNU Screen through 4.8.0 allows remote attackers to cause a denial of service (invalid write access and application crash) or possibly have unspecified other impact via a crafted UTF-8 character sequence.
CVE-2021-26934 2 Fedoraproject, Linux 2 Fedora, Linux Kernel 2023-11-07 4.6 MEDIUM 7.8 HIGH
An issue was discovered in the Linux kernel 4.18 through 5.10.16, as used by Xen. The backend allocation (aka be-alloc) mode of the drm_xen_front drivers was not meant to be a supported configuration, but this wasn't stated accordingly in its support status entry.
CVE-2021-26933 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2023-11-07 2.1 LOW 5.5 MEDIUM
An issue was discovered in Xen 4.9 through 4.14.x. On Arm, a guest is allowed to control whether memory accesses are bypassing the cache. This means that Xen needs to ensure that all writes (such as the ones during scrubbing) have reached the memory before handing over the page to a guest. Unfortunately, the operation to clean the cache is happening before checking if the page was scrubbed. Therefore there is no guarantee when all the writes will reach the memory.
CVE-2021-26927 2 Fedoraproject, Jasper Project 2 Fedora, Jasper 2023-11-07 4.3 MEDIUM 5.5 MEDIUM
A flaw was found in jasper before 2.0.25. A null pointer dereference in jp2_decode in jp2_dec.c may lead to program crash and denial of service.
CVE-2021-26926 2 Fedoraproject, Jasper Project 2 Fedora, Jasper 2023-11-07 5.8 MEDIUM 7.1 HIGH
A flaw was found in jasper before 2.0.25. An out of bounds read issue was found in jp2_decode function whic may lead to disclosure of information or program crash.
CVE-2021-26925 2 Fedoraproject, Roundcube 2 Fedora, Webmail 2023-11-07 3.5 LOW 5.4 MEDIUM
Roundcube before 1.4.11 allows XSS via crafted Cascading Style Sheets (CSS) token sequences during HTML email rendering.

CVE-2021-25288 2 Fedoraproject, Python 2 Fedora, Pillow 2023-11-07 6.4 MEDIUM 9.1 CRITICAL
An issue was discovered in Pillow before 8.2.0. There is an out-of-bounds read in J2kDecode, in j2ku_gray_i.
CVE-2021-25287 2 Fedoraproject, Python 2 Fedora, Pillow 2023-11-07 6.4 MEDIUM 9.1 CRITICAL

CVE-2021-25219 6 Debian, Fedoraproject, Isc and 3 more 23 Debian Linux, Fedora, Bind and 20 more 2023-11-07 5.0 MEDIUM 5.3 MEDIUM
In BIND 9.3.0 -> 9.11.35, 9.12.0 -> 9.16.21, and versions 9.9.3-S1 -> 9.11.35-S1 and 9.16.8-S1 -> 9.16.21-S1 of BIND Supported Preview Edition, as well as release versions 9.17.0 -> 9.17.18 of the BIND 9.17 development branch, exploitation of broken authoritative servers using a flaw in response processing can cause degradation in BIND resolver performance. The way the lame cache is currently designed makes it possible for its internal data structures to grow almost infinitely, which may cause significant delays in client query processing.
CVE-2021-25218 2 Fedoraproject, Isc 2 Fedora, Bind 2023-11-07 5.0 MEDIUM 7.5 HIGH
In BIND 9.16.19, 9.17.16. Also, version 9.16.19-S1 of BIND Supported Preview Edition When a vulnerable version of named receives a query under the circumstances described above, the named process will terminate due to a failed assertion check. The vulnerability affects only BIND 9 releases 9.16.19, 9.17.16, and release 9.16.19-S1 of the BIND Supported Preview Edition.
CVE-2021-25217 5 Debian, Fedoraproject, Isc and 2 more 26 Debian Linux, Fedora, Dhcp and 23 more 2023-11-07 3.3 LOW 7.4 HIGH
In ISC DHCP 4.1-ESV-R1 -> 4.1-ESV-R16, ISC DHCP 4.4.0 -> 4.4.2 (Other branches of ISC DHCP (i.e., releases in the 4.0.x series or lower and releases in the 4.3.x series) are beyond their End-of-Life (EOL) and no longer supported by ISC. From inspection it is clear that the defect is also present in releases from those series, but they have not been officially tested for the vulnerability), The outcome of encountering the defect while reading a lease that will trigger it varies, according to: the component being affected (i.e., dhclient or dhcpd) whether the package was built as a 32-bit or 64-bit binary whether the compiler flag -fstack-protection-strong was used when compiling In dhclient, ISC has not successfully reproduced the error on a 64-bit system. However, on a 32-bit system it is possible to cause dhclient to crash when reading an improper lease, which could cause network connectivity problems for an affected system due to the absence of a running DHCP client process. In dhcpd, when run in DHCPv4 or DHCPv6 mode: if the dhcpd server binary was built for a 32-bit architecture AND the -fstack-protection-strong flag was specified to the compiler, dhcpd may exit while parsing a lease file containing an objectionable lease, resulting in lack of service to clients. Additionally, the offending lease and the lease immediately following it in the lease database may be improperly deleted. if the dhcpd server binary was built for a 64-bit architecture OR if the -fstack-protection-strong compiler flag was NOT specified, the crash will not occur, but it is possible for the offending lease and the lease which immediately followed it to be improperly deleted.
CVE-2021-25215 6 Debian, Fedoraproject, Isc and 3 more 25 Debian Linux, Fedora, Bind and 22 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
In BIND 9.0.0 -> 9.11.29, 9.12.0 -> 9.16.13, and versions BIND 9.9.3-S1 -> 9.11.29-S1 and 9.16.8-S1 -> 9.16.13-S1 of BIND Supported Preview Edition, as well as release versions 9.17.0 -> 9.17.11 of the BIND 9.17 development branch, when a vulnerable version of named receives a query for a record triggering the flaw described above, the named process will terminate due to a failed assertion check. The vulnerability affects all currently maintained BIND 9 branches (9.11, 9.11-S, 9.16, 9.16-S, 9.17) as well as all other versions of BIND 9.
CVE-2021-25214 5 Debian, Fedoraproject, Isc and 2 more 24 Debian Linux, Fedora, Bind and 21 more 2023-11-07 4.0 MEDIUM 6.5 MEDIUM
In BIND 9.8.5 -> 9.8.8, 9.9.3 -> 9.11.29, 9.12.0 -> 9.16.13, and versions BIND 9.9.3-S1 -> 9.11.29-S1 and 9.16.8-S1 -> 9.16.13-S1 of BIND 9 Supported Preview Edition, as well as release versions 9.17.0 -> 9.17.11 of the BIND 9.17 development branch, when a vulnerable version of named receives a malformed IXFR triggering the flaw described above, the named process will terminate due to a failed assertion the next time the transferred secondary zone is refreshed.
