Ubuntu 20.04 ESM : Nanopb vulnerabilities (USN-6121-1)

The remote Ubuntu 20.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6121-1 advisory. It was discovered that Nanopb incorrectly handled certain decode messages. An attacker could possibly use this cause a denial of service or expose...

SUSE CVE-2020-5235

There is a potentially exploitable out of memory condition In Nanopb before 0.4.1, 0.3.9.5, and 0.2.9.4. When nanopb is compiled with PBENABLEMALLOC, the message to be decoded contains a repeated string, bytes or message field and realloc runs out of memory when expanding the array nanopb can end...

SUSE CVE-2020-26243

Nanopb is a small code-size Protocol Buffers implementation. In Nanopb before versions 0.4.4 and 0.3.9.7, decoding specifically formed message can leak memory if dynamic allocation is enabled and an oneof field contains a static submessage that contains a dynamic field, and the message being...

SUSE CVE-2021-21401

Nanopb is a small code-size Protocol Buffers implementation in ansi C. In Nanopb before versions 0.3.9.8 and 0.4.5, decoding a specifically formed message can cause invalid free or realloc calls if the message type contains an oneof field, and the oneof directly contains both a pointer field and ...

CVE-2022-20203

In multiple locations of the nanopb library, there is a possible way to corrupt memory when decoding untrusted protobuf files. This could lead to local escalation of privilege,with no additional execution privileges needed. User interaction is not needed for exploitation...

CVE-2022-20203

The CVE-2022-20203 entry refers to a memory corruption vulnerability in the nanopb library, arising in multiple locations during decoding of untrusted protobufs. This can lead to local escalation of privilege with no extra privileges or user interaction required. Available connected sources (e.g....

Nanopb 缓冲区错误漏洞

Nanopb is a protocol buffer implementation for microprocessors from the individual developer of Nanopb. A security vulnerability exists in Nanopb that stems from a potential memory corruption when decoding an untrusted protobuf file. An attacker can exploit this vulnerability to perform a local...

PT-2022-14432 · Nanopb · Nanopb

Name of the Vulnerable Software and Affected Versions: nanopb library affected versions not specified Description: The issue concerns the nanopb library, where decoding untrusted protobuf files can lead to memory corruption. This could result in local escalation of privilege without requiring...

Denial Of Service (DoS)

Nanopb is vulnerable to denial of service. Decoding a specifically formed message can cause invalid free or realloc calls if the message type contains an oneof field, and the oneof directly contains both a pointer field and a non-pointer field. If the message data first contains the non-pointer...
