In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix oob access in cgroup local storage
Lonial reported that an out-of-bounds access in cgroup local storage
can be crafted via tail calls. Given two programs each utilizing a
cgroup local storage with a different value size, and one program
doing a tail call into the other. The verifier will validate each of
the indivial programs just fine. However, in the runtime context
the bpf_cg_run_ctx holds an bpf_prog_array_item which contains the
BPF program as well as any cgroup local storage flavor the program
uses. Helpers such as bpf_get_local_storage() pick this up from the
runtime context:
ctx = container_of(current->bpf_ctx, struct bpf_cg_run_ctx, run_ctx);
storage = ctx->prog_item->cgroup_storage[stype];
if (stype == BPF_CGROUP_STORAGE_SHARED)
ptr = &READ_ONCE(storage->buf)->data[0];
else
ptr = this_cpu_ptr(storage->percpu_buf);
For the second program which was called from the originally attached
one, this means bpf_get_local_storage() will pick up the former
program's map, not its own. With mismatching sizes, this can result
in an unintended out-of-bounds access.
To fix this issue, we need to extend bpf_map_owner with an array of
storage_cookie[] to match on i) the exact maps from the original
program if the second program was using bpf_get_local_storage(), or
ii) allow the tail call combination if the second program was not
using any of the cgroup local storage maps.
A vulnerability has been identified in SINEC Traffic Analyzer (6GK8822-1BG01-0BA0) (All versions). The affected application uses a monitoring interface that is not operating in a strictly passive mode. This could allow an attacker to interact with the interface, leading to man-in-the-middle attacks.
A vulnerability has been identified in Simcenter Femap V2406 (All versions < V2406.0003), Simcenter Femap V2412 (All versions < V2412.0002). The affected applications contain an out of bounds write vulnerability when parsing a specially crafted STP file. This could allow an attacker to execute code in the context of the current process.(ZDI-CAN-26692)
A vulnerability has been identified in Simcenter Femap V2406 (All versions < V2406.0003), Simcenter Femap V2412 (All versions < V2412.0002). The affected applications contains an out of bounds read vulnerability while parsing specially crafted BMP files. This could allow an attacker to execute code in the context of the current process.
A vulnerability has been identified in SINEC Traffic Analyzer (6GK8822-1BG01-0BA0) (All versions < V3.0). The affected application runs docker containers without adequate resource and security limitations. This could allow an attacker to perform a denial-of-service (DoS) attack.
A vulnerability has been identified in SINEC Traffic Analyzer (6GK8822-1BG01-0BA0) (All versions < V3.0). The affected application runs docker containers without adequate security controls to enforce isolation. This could allow an attacker to gain elevated access, potentially accessing sensitive host system resources.
A vulnerability has been identified in SINEC Traffic Analyzer (6GK8822-1BG01-0BA0) (All versions < V3.0). The affected application exposes an internal service port to be accessible from outside the system. This could allow an unauthorized attacker to access the application.
A vulnerability has been identified in SIMATIC RTLS Locating Manager (All versions < V3.2). Affected products do not properly validate input for a backup script. This could allow an authenticated remote attacker with high privileges in the application to execute arbitrary code with 'NT Authority/SYSTEM' privileges.
A vulnerability has been identified in SIMATIC RTLS Locating Manager (All versions < V3.3). Affected SIMATIC RTLS Locating Manager Report Clients do not properly protect credentials that are used to authenticate to the server. This could allow an authenticated local attacker to extract the credentials and use them to escalate their access rights from the Manager to the Systemadministrator role.
A vulnerability has been identified in SIMATIC RTLS Locating Manager (All versions < V3.3). Affected devices do not properly validate input sent to its listening port on the local loopback interface. This could allow an unauthenticated local attacker to cause a denial of service condition.
