Summary
list_item_verbose in tar/util.c in libarchive through 3.7.7 does not check an strftime return value, which can lead to a denial of service or unspecified other impact via a crafted TAR archive that is read with a verbose value of 2. For example, the 100-byte buffer may not be sufficient for a custom locale.

Title
Grub2: commands/extcmd: missing check for failed allocation
Summary
A flaw was found in grub2 where the grub_extcmd_dispatcher() function calls grub_arg_list_alloc() to allocate memory for the grub's argument list. However, it fails to check in case the memory allocation fails. Once the allocation fails, a NULL point will be processed by the parse_option() function, leading grub to crash or, in some rare scenarios, corrupt the IVT data.

Title
A malformed Contact or Record-Route URI in an incoming SIP request can cause Asterisk to crash when res_resolver_unbound is used
Summary
Asterisk is an open-source private branch exchange (PBX). Prior to versions 18.24.3, 20.9.3, and 21.4.3 of Asterisk and versions 18.9-cert12 and 20.7-cert2 of certified-asterisk, if Asterisk attempts to send a SIP request to a URI whose host portion starts with `.1` or `[.1]`, and res_resolver_unbound is loaded, Asterisk will crash with a SEGV. To receive a patch, users should upgrade to one of the following versions: 18.24.3, 20.9.3, 21.4.3, certified-18.9-cert12, certified-20.7-cert2. Two workarounds are available. Disable res_resolver_unbound by setting `noload = res_resolver_unbound.so` in modules.conf, or set `rewrite_contact = yes` on all PJSIP endpoints. NOTE: This may not be appropriate for all Asterisk configurations.

Title
Junos OS and Junos OS Evolved: Receipt of specific PIM packet causes rpd crash when PIM is configured along with MoFRR
Summary
An Unchecked Return Value vulnerability in the Routing Protocol Daemon (rpd) on Juniper Networks Junos OS and Juniper Networks Junos OS Evolved allows a logically adjacent, unauthenticated attacker sending a specific PIM packet to cause rpd to crash and restart, resulting in a Denial of Service (DoS), when PIM is configured with Multicast-only Fast Reroute (MoFRR). Continued receipt and processing of this packet may create a sustained Denial of Service (DoS) condition.
This issue is observed on Junos and Junos Evolved platforms where PIM is configured along with MoFRR. MoFRR tries to select the active path, but due to an internal timing issue, rpd is unable to select the forwarding next-hop towards the source, resulting in an rpd crash.
This issue affects:
Junos OS:
* All versions before 20.4R3-S10,
* from 21.2 before 21.2R3-S7,
* from 21.4 before 21.4R3-S6,
* from 22.1 before 22.1R3-S5,
* from 22.2 before 22.2R3-S3,
* from 22.3 before 22.3R3,
* from 22.4 before 22.4R2;
Junos OS Evolved:
* All versions before 20.4R3-S10 -EVO,
* All versions of 21.2-EVO,
* from 21.4-EVO before 21.4R3-S9-EVO,
* from 22.1-EVO before 22.1R3-S5-EVO,
* from 22.2-EVO before 22.2R3-S3-EVO,
* from 22.3-EVO before 22.3R3-EVO,
* from 22.4-EVO before 22.4R2-EVO.

Mitigation MIT-53
Implementation
Check the results of all functions that return a value and verify that the value is expected.
Mitigation MIT-56
Implementation
For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].
Mitigation
Implementation
Ensure that you account for all possible return values from the function.
Mitigation
Implementation
When designing a function, make sure you return a value or throw an exception in case of an error.
No CAPEC attack patterns related to this CWE.
