9/17/2023 0 Comments Irip 2.0If your application does not have user input, it is unlikely to be affected. ODBCAppender enabled for logging messages to, generally done via a config fileģ. Log4cxx compiled with ODBC support(before version 1.1.0, this was auto-detected at compile time)Ģ. Three preconditions must be met for this vulnerability to be possible:ġ. As of version 1.1.0, this must be both explicitly enabled in order to be compiled in. Note that Log4cxx is a C++ framework, so only C++ applications are affected.īefore version 1.1.0, the ODBC appender was automatically part of Log4cxx if the library was found when compiling the library. This has been the case since at least version 0.9.0(released ) No fields sent to the database were properly escaped for SQL injection. SQL injection in Log4cxx when using the ODBC appender to send log messages to a database. The SPDM specification (DSP0274) does not contain this vulnerability. Older branches are not maintained, but users of the 2.3 branch may receive a patch in version 2.3.2. The SPDM responder is not impacted if mutual authentication is not required. The SPDM responder is not impacted if `KEY_EX_CAP=0` or `PSK_CAP=0` or `PSK_CAP=01b`. This issue only impacts the SPDM responder, which supports `KEY_EX_CAP=1 and `PSK_CAP=10b` at same time with mutual authentication requirement. The session hashes would be expected to fail in this case, but the condition was not detected. This is most likely to happen when the Requester begins a session using one method (DHE, for example) and then uses the other method's finish (PSK_FINISH in this example) to establish the session. If a device supports both DHE session and PSK session with mutualĪuthentication, the attacker may be able to establish the session with `KEY_EXCHANGE` and `PSK_FINISH` to bypass the mutual authentication. A vulnerability has been identified in SPDM session establishment in libspdm prior to version 2.3.1. Libspdm is a sample implementation that follows the DMTF SPDM specifications. As a workaround, users can apply Contiki-NG pull request #2271 to patch the problem directly. The problem has been patched in the `develop` branch of Contiki-NG, and will be included in the upcoming 4.9 release. The resulting pointer is used without a check, leading to the dereference of a NULL pointer of type `uip_ds6_nbr_t`. The message handler does not check for RS messages with an SLLAO that indicates a link-layer address change that a neighbor entry can actually be created for the indicated address. If the indicated source address changes, a given neighbor entry is set to the STALE state. The ND protocol includes a message type called Router Solicitation (RS), which is used to locate routers and update their address information via the SLLAO (Source Link-Layer Address Option). Contiki-NG contains an implementation of IPv6 Neighbor Discovery (ND) in the module `os/net/ipv6/uip-nd6.c`. The Contiki-NG operating system versions 4.8 and prior can be triggered to dereference a NULL pointer in the message handling code for IPv6 router solicitiations. One proposed fix for this vulnerability is to patch `Decompress.c:887` by breaking `if(len <= 0)`, which has been incorporated in version via commit bab062bde40b2ae8a91eecd522e84d8b993bab58. Consequently, the program exits with an error code of 64, causing a Denial of Service. This value is then passed to the `decomp_append_bytes` function without proper validation, causing the program to attempt to allocate a massive chunk of memory that is impossible to allocate. When handling a DNS packet with an Answer RR of qtype 16 (TXT record) and any qclass, if the `rdlength` is smaller than `rdata`, the result of the line `Decompress.c:886` is a negative number `len = rdlength - total `. The vulnerability exists in the `decomp_get_rddata` function within the `Decompress.c` file. In version and prior, a remotely exploitable integer underflow vulnerability in the DNS packet decompression function allows an attacker to cause a Denial of Service by triggering an abnormal program termination.
