When the ngx_mail_auth_http_module module is enabled on NGINX Plus or NGINX Open Source, undisclosed requests can cause worker processes to terminate. This issue may occur when (1) CRAM-MD5 or APOP authentication is enabled, and (2) the authentication server permits retry by returning the Auth-Wait response header. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

There is a NULL pointer dereference in the syscall open_exec function of Allwinner R818 SoC Android Q SDK V1.0 that could executable a malicious file to cause a system crash.

Due to missing nil check, sending 0x0a-0x0f HTTP/2 frames will cause a running server to panic

A NULL pointer dereference in the safe_atou64 function (src/misc.c) of owntone-server through commit c4d57aa allows attackers to cause a Denial of Service (DoS) via sending a series of crafted HTTP requests to the server.

LibVNCServer versions 0.9.15 and prior (fixed in commit dc78dee) contain null pointer dereference vulnerabilities in the HTTP proxy handlers within httpProcessInput() in httpd.c that allow remote attackers to cause a denial of service by sending specially crafted HTTP requests. Attackers can exploit missing validation of strchr() return values in the CONNECT and GET proxy handling paths to trigger null pointer dereferences and crash the server when httpd and proxy features are enabled.

A NULL pointer dereference in the daap_reply_playlists function (src/httpd_daap.c) of owntone-server commit 3d1652d allows attackers to cause a Denial of Service (DoS) via sending a crafted DAAP request to the server

An issue was discovered in Oniguruma 6.2.0, as used in Oniguruma-mod in Ruby through 2.4.1 and mbstring in PHP through 7.1.5. A SIGSEGV occurs in left_adjust_char_head() during regular expression compilation. Invalid handling of reg->dmax in forward_search_range() could result in an invalid pointer dereference, normally as an immediate denial-of-service condition.

The lexer_process_char_literal function in jerry-core/parser/js/js-lexer.c in JerryScript 1.0 does not skip memory allocation for empty strings, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via malformed JavaScript source code, related to the jmem_heap_free_block function.

free5GC SMF provides Session Management Function for free5GC, an open-source project for 5th generation (5G) mobile core networks. In versions up to and including 1.4.1, SMF panics due to nil pointer dereference and the SMF process terminates. This is triggered by a malformed PFCP SessionReportRequest on the SMF PFCP (UDP/8805) interface. No known upstream fix is available, but some workarounds are available. ACL/firewall the PFCP interface so only trusted UPF IPs can reach SMF (reduce spoofing/abuse surface); drop/inspect malformed PFCP SessionReportRequest messages at the network edge where feasible, and/or add recover() around PFCP handler dispatch to avoid whole-process termination (mitigation only).

free5GC SMF provides Session Management Function for free5GC, an open-source project for 5th generation (5G) mobile core networks.

Null pointer dereference vulnerability exists in multiple vendors MFPs and printers which implement Debut web server 1.2 or 1.3. Processing a specially crafted request may lead an affected product to a denial-of-service (DoS) condition. As for the affected products/models/versions, see the detailed information provided by each vendor.

A vulnerability was found in openldap. This security flaw causes a null pointer dereference in ber_memalloc_x() function.

SAMtools is a program for reading, manipulating and writing bioinformatics file formats. Starting in version 1.17, in the cram-size command, used to write information about how well CRAM files are compressed, a check to see if the `cram_decode_compression_header()` was missing. If the function returned an error, this could lead to a NULL pointer dereference. Exploiting this bug causes a NULL pointer dereference. Typically this will cause the program to crash. Versions 1.23.1, 1.22.2 and 1.21.1 include fixes for this issue. There is no workaround for this issue.
