The podman packages version podman-1.6.4-32.el79 as released for Red Hat Enterprise Linux 7 Extras via RHSA-2022:2190 (https://access.redhat.com/errata/RHSA-2022:2190) included an incorrect version of podman that was missing multiple bug and security fixes. One of the fixes regressed in that update was the fix for CVE-2020-14370, that was previously corrected in the podman packages in Red Hat Enterprise Linux 7 Extras via RHSA-2020:5056 (https://access.redhat.com/errata/RHSA-2020:5056). The CVE-2022-2739 was assigned to this security regression and it is specific to the podman packages produced by Red Hat.

The original issue - CVE-2020-14370 - could possibly allow an attacker to gain access to sensitive information stored in environment variables. For more details about the original issue, see:

A flaw was found in the way samba implemented SMB1 authentication. An attacker could use this flaw to retrieve the plaintext password sent over the wire even if Kerberos authentication was required.

IBM Java Security Components in IBM SDK, Java Technology Edition 8 before SR1 FP10, 7 R1 before SR3 FP10, 7 before SR9 FP10, 6 R1 before SR8 FP7, 6 before SR16 FP7, and 5.0 before SR16 FP13 stores plaintext information in memory dumps, which allows local users to obtain sensitive information by reading a file.

An unspecified vulnerability in Java SE related to the Deployment component could allow an unauthenticated attacker to cause low confidentiality impact, low integrity impact, and no availability impact.

A NULL pointer dereference flaw was discovered in the DrawGlyphList class in the 2D component in OpenJDK. A specially crafted font file could use this flaw to cause a Java application to crash.

An unspecified vulnerability in Java SE related to the JAXP component could allow an unauthenticated attacker to cause a denial of service resulting in a low availability impact using unknown attack vectors.

An unspecified vulnerability in Java SE related to the Concurrency component could allow an unauthenticated attacker to cause a denial of service resulting in a low availability impact using unknown attack vectors.

A flaw was discovered in fence-agents, prior to version 4.3.4, where using non-ASCII characters in a guest VM's comment or other fields would cause fencerhevm to exit with an exception. In cluster environments, this could lead to preventing automated recovery or otherwise denying service to clusters of which that VM is a member.

In elfutils 0.175, a negative-sized memcpy is attempted in elfcvtnote in libelf/notexlate.h because of an incorrect overflow check. Crafted elf input causes a segmentation fault, leading to denial of service (program crash).

An issue was discovered in sd-bus in systemd 239. busprocessobject() in libsystemd/sd-bus/bus-objects.c allocates a variable-length stack buffer for temporarily storing the object path of incoming D-Bus messages. An unprivileged local user can exploit this by sending a specially crafted message to PID1, causing the stack pointer to jump over the stack guard pages into an unmapped memory region and trigger a denial of service (systemd PID1 crash and kernel panic).

Docker Engine before 18.09 allows attackers to cause a denial of service (dockerd memory consumption) via a large integer in a --cpuset-mems or --cpuset-cpus value, related to daemon/daemonunix.go, pkg/parsers/parsers.go, and pkg/sysinfo/sysinfo.go.

A flaw was found in Poppler 0.72.0. The PDFDoc::setup class in PDFDoc.cc allows attackers to cause a denial-of-service (application crash caused by Object.h SIGABRT, because of a wrong return value from PDFDoc::setup) by crafting a PDF file in which an xref data structure is mishandled during extractPDFSubtype processing.

There is a SEGV in Exiv2::Internal::TiffParserWorker::findPrimaryGroups of tiffimageint.cpp in Exiv2 0.27-RC3. A crafted input will lead to a denial of service attack.

A flaw was found in systemd-journald. An out-of-bounds read when parsing a crafted syslog message that could lead to information disclosure.

An issue was found in Exiv2 0.26 and previous versions. A heap-based buffer over-read in PngChunk::readRawProfile function in pngchunkint.cpp may cause a denial of service via a crafted PNG file.

A security issue was found that could allow any users with Editor or Admin permissions in Grafana to read any file that the Grafana process can read from the filesystem. Note, that in order to exploit this you would need to be logged in to the system as a legitimate user with Editor or Admin permissions.

An issue was discovered in Poppler 0.71.0. There is a memory leak in GfxColorSpace::setDisplayProfile in GfxState.cc, as demonstrated by pdftocairo.

A vulnerability was found in Gluster's features/locks translator An user-controlled string is given to snprintf without a proper format string. Sending a specially crafted string would result in a denial of service.

The Gluster file system through versions 4.1.4 and 3.1.2 is vulnerable to a denial of service attack via use of the 'GFXATTRIOSTATSDUMPKEY' xattr. A remote, authenticated attacker could exploit this by mounting a Gluster volume and repeatedly calling 'setxattr(2)' to trigger a state dump and create an arbitrary number of files in the server's runtime directory.

A flaw was found in glusterfs server through versions 4.1.4 and 3.1.2 which allowed repeated usage of GFMETALOCKKEY xattr. A remote, authenticated attacker could use this flaw to create multiple locks for single inode by using setxattr repetitively resulting in memory exhaustion of glusterfs server node.

It was discovered that sos-collector does not properly set the default permissions of newly created files, making all files created by the tool readable by any local user. A local attacker may use this flaw by waiting for a legit user to run sos-collector and steal the collected data in the /var/tmp directory.

The Gluster file system through versions 3.12 and 4.1.4 is vulnerable to a buffer overflow in the 'features/index' translator via the code handling the 'GFXATTRCLRLKCMD' xattr in the 'plgetxattr' function. A remote authenticated attacker could exploit this on a mounted volume to cause a denial of service.

The Linux kernel before 4.15-rc8 was found to be vulnerable to a NULL pointer dereference bug in the netlinknscapable() function in the net/netlink/afnetlink.c file. A local attacker could exploit this when a net namespace with a netnsid is assigned to cause a kernel panic and a denial of service.

A flaw was found in RPC request using gfs3renamereq in glusterfs server. An authenticated attacker could use this flaw to write to a destination outside the gluster volume.

It was found that Diffie Hellman Client key exchange handling in NSS 3.21.x was vulnerable to small subgroup confinement attack. An attacker could use this flaw to recover private keys by confining the client DH key to small subgroup of the desired group.

A flaw was found in Red Hat Ceph before 0.94.9-8. The way Ceph Object Gateway handles POST object requests permits an authenticated attacker to launch a denial of service attack by sending null or specially crafted POST object requests.

An issue was discovered in mspack/chmd.c in libmspack before 0.7alpha. ...

A flaw was found in GlusterFS. A NULL pointer dereference vulnerability due to an improper implementation of the posixgetfilecontents function. An attacker could exploit this to perform a Denial of Service attack.

A flaw was found in GlusterFS. An Information Exposure vulnerability due to an improper implementation of the glusterfs.file function. An attacker could exploit this to obtain information about the files available.

Oracle Java SE 6u201, 7u191, 8u181, and 10.0.2 fixes an unspecified vulnerability in the JSSE component (CVE-2018-2973). Upstream has CVSS scored this issue as: 5.9/CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N
