Vulnerabilidades

mouse07410/asn1c is an ASN.1 compiler. In 1.4 and earlier, a memory safety vulnerability was identified in the OER decoding skeleton files generated by asn1c (specifically INTEGER_oer.c). When parsing a maliciously crafted, zero-length OER payload for a variable-length, non-negative INTEGER type, the decoder fails to…

An issue was discovered in mouse07410 asn1c thru 0.9.29 (2025-03-20) - a fork of vlm asn1c. In UPER (Unaligned Packed Encoding Rules), asn1c-generated decoders fail to enforce INTEGER constraints when the bound is positive and exceeds 32 bits in length, potentially allowing incorrect or malicious input to be processed.

An issue was discovered in asn1c through v0.9.28. A NULL pointer dereference exists in the function _default_error_logger() located in asn1fix.c. It allows an attacker to cause Denial of Service.

Stack-based buffer overflow vulnerability in asn1c through v0.9.28 via function genhash_get in genhash.c.

The asn1f_lookup_symbol_impl function in asn1fix_retrieve.c in libasn1fix.a in asn1c 0.9.28 allows remote attackers to cause a denial of service (segmentation fault) via a crafted .asn1 file.

Integer overflow in the rtxMemHeapAlloc function in asn1rt_a.lib in Objective Systems ASN1C for C/C++ before 7.0.2 allows context-dependent attackers to execute arbitrary code or cause a denial of service (heap-based buffer overflow), on a system running an application compiled by ASN1C, via crafted ASN.1 data.
