tcpdump: Buffer over-read in ospf6_print_lshdr() function in print-ospf6.c

The OSPFv3 parser in tcpdump before 4.9.3 has a buffer over-read in print-ospf6.c:ospf6_print_lshdr().

389-ds-base: Mishandled search requests in servers/slapd/search.c:do_search() allows for denial of service

A flaw was found in 389 Directory Server. A specially crafted search query could lead to excessive CPU consumption in the do_search() function. An unauthenticated attacker could use this flaw to provoke a denial of service.

389-ds-base: Crash in delete_passwdPolicy when persistent search connections are terminated unexpectedly

A flaw was found in 389-ds-base before version 1.3.8.4-13. The process ns-slapd crashes in delete_passwdPolicy function when persistent search connections are terminated unexpectedly leading to remote denial of service.

389-ds-base: Server crash through modify command with large DN

A vulnerability was discovered in 389-ds-base through versions 1.3.7.10, 1.3.8.8 and 1.4.0.16. The lock controlling the error log was not correctly used when re-opening the log file in log__error_emergency(). An attacker could send a flood of modifications to a very large DN, which would cause slapd to crash.

libX11: Off-by-one error in XListExtensions in ListExt.c

An issue was discovered in libX11 through 1.6.5. The function XListExtensions in ListExt.c is vulnerable to an off-by-one error caused by malicious server responses, leading to DoS or possibly unspecified other impact.

libX11: Crash on invalid reply in XListExtensions in ListExt.c

An issue was discovered in XListExtensions in ListExt.c in libX11 through 1.6.5. A malicious server can send a reply in which the first string overflows, causing a variable to be set to NULL that will be freed later on, leading to DoS (segmentation fault).

gd: NULL pointer dereference in gdImageClone

gdImageClone in gd.c in libgd 2.1.0-rc2 through 2.2.5 has a NULL pointer dereference allowing attackers to crash an application via a specific function call sequence. Only affects PHP when linked with an external libgd (not bundled).

libjpeg-turbo: heap-based buffer over-read via crafted 8-bit BMP in get_8bit_row in rdbmp.c leads to denial of service

get_8bit_row in rdbmp.c in libjpeg-turbo through 1.5.90 and MozJPEG through 3.3.1 allows attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted 8-bit BMP in which one or more of the color indices is out of range for the number of palette entries.

tcpdump: Buffer over-read in ikev1_n_print() function in print-isakmp.c

The IKEv1 parser in tcpdump before 4.9.3 has a buffer over-read in print-isakmp.c:ikev1_n_print().

tcpdump: Buffer over-read in print-icmp6.c

The Rx parser in tcpdump before 4.9.3 has a buffer over-read in print-rx.c:rx_cache_find() and rx_cache_insert().

tcpdump: Buffer over-read in lmp_print_data_link_subobjs() function in print-lmp.c

The LMP parser in tcpdump before 4.9.3 has a buffer over-read in print-lmp.c:lmp_print_data_link_subobjs().

tcpdump: Buffer over-read in vrrp_print() function in print-vrrp.c

The VRRP parser in tcpdump before 4.9.3 has a buffer over-read in print-vrrp.c:vrrp_print() for VRRP version 2, a different vulnerability than CVE-2019-15167.

libcgroup: cgrulesengd creates log files with insecure permissions

libcgroup up to and including 0.41 creates /var/log/cgred with mode 0666 regardless of the configured umask, leading to disclosure of information.

kernel: Missing check in fs/inode.c:inode_init_owner() does not clear SGID bit on non-directories for non-members

The inode_init_owner function in fs/inode.c in the Linux kernel through 3.16 allows local users to create files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose group ownership is that group. The intended behavior was that the non-member can trigger creation of a directory (but not a plain file) whose group ownership is that group. The non-member can escalate privileges by making the plain file executable and SGID.

jetty: large settings frames causing denial of service

In Eclipse Jetty version 9.3.x and 9.4.x, the server is vulnerable to Denial of Service conditions if a remote client sends either large SETTINGs frames container containing many settings, or many small SETTINGs frames. The vulnerability is due to the additional CPU and memory allocations required to handle changed settings.

hw: Machine Check Error on Page Size Change (IFU)

Improper invalidation for page table updates by a virtual guest operating system for multiple Intel(R) Processors may allow an authenticated user to potentially enable denial of service of the host system via local access.

pdfbox: unbounded computation in parser resulting in a denial of service

In Apache PDFBox 1.8.0 to 1.8.15 and 2.0.0RC1 to 2.0.11, a carefully crafted PDF file can trigger an extremely long running computation when parsing the page tree.

An issue was discovered in the Security component in Symfony 2.7.x before 2.7.48, 2.8.x before 2.8.41, 3.3.x before 3.3.17, 3.4.x before 3.4.11, and 4.0.x before 4.0.11. A session fixation vulnerability within the "Guard" login feature may allow an attacker to impersonate a victim towards the web application if the session id value was previously known to the attacker.

389-ds-base: replication and the Retro Changelog plugin store plaintext password by default

389-ds-base before versions 1.3.8.5, 1.4.0.12 is vulnerable to a Cleartext Storage of Sensitive Information. By default, when the Replica and/or retroChangeLog plugins are enabled, 389-ds-base stores passwords in plaintext format in their respective changelog files. An attacker with sufficiently high privileges, such as root or Directory Manager, can query these files in order to retrieve plaintext passwords.

sssd: information leak from the sssd-sudo responder

The UNIX pipe which sudo uses to contact SSSD and read the available sudo rules from SSSD has too wide permissions, which means that anyone who can send a message using the same raw protocol that sudo and SSSD use can read the sudo rules available for any user. This affects versions of SSSD before 1.16.3.
