EUVD-2026-35474

Issue summary: A signed integer overflow when sizing the destination buffer for Unicode output in ASN1mbstringncopy can lead to a heap buffer overflow. Impact summary: A heap buffer overflow may lead to a crash or possibly attacker controlled code execution or other undefined behaviour. In...

USN-8414-2 openssl, openssl1.0 vulnerabilities

USN-8414-1 fixed several vulnerabilities in OpenSSL. This update provides the corresponding update for Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, and Ubuntu 20.04 LTS. Original advisory details: Frank Buss discovered that OpenSSL had a heap buffer over-read in ASN.1 content parsing. An...

Heap-based Buffer Overflow

Overview Affected versions of this package are vulnerable to Heap-based Buffer Overflow in ASN1mbstringncopy and ASN1mbstringcopy. An attacker supplying input on the order of 2^30 characters can overflow the signed int destination size computation for Unicode output, wrapping the allocation size ...

CVE-2026-7383

Issue summary: A signed integer overflow when sizing the destination buffer for Unicode output in ASN1mbstringncopy can lead to a heap buffer overflow. Impact summary: A heap buffer overflow may lead to a crash or possibly attacker controlled code execution or other undefined behaviour. In...

CVE-2026-7383

OpenSSL is vulnerable to a signed integer overflow when sizing the destination buffer for Unicode output in ASN1_mbstring_ncopy() . This occurs because the destination size for BMPSTRING (UTF-16), UNIVERSALSTRING (UTF-32), and UTF8STRING is computed using signed integers, which can overflow when ...

CVE-2026-7383 Possible Heap Buffer Overflow in ASN.1 Multibyte String Conversion

Issue summary: A signed integer overflow when sizing the destination buffer for Unicode output in ASN1mbstringncopy can lead to a heap buffer overflow. Impact summary: A heap buffer overflow may lead to a crash or possibly attacker controlled code execution or other undefined behaviour. In...

CVE-2026-49762

Uncontrolled Resource Consumption vulnerability in the Elixir standard library's Version module allows an attacker who controls a version string to cause a denial of service through CPU and memory exhaustion. The version parser converts numeric version components major, minor, patch and numeric...

CVE-2026-11792 389-ds-base: 389-ds-base: heap buffer overflow in audit log password masking (create_masked_entry_string)

A heap buffer overflow flaw was found in 389 Directory Server. When audit logging is enabled, the createmaskedentrystring function in auditlog.c copies a fixed-length password mask into a precisely-sized heap buffer without checking available space. If a short cleartext password is logged requiri...

CVE-2026-11787

The CVE-2026-11787 entry concerns 389 Directory Server (389-ds-base). A heap buffer over-read occurs in the ldap_utf8prev() function when reading bytes before the start of a buffer during string filter parsing (via str2simple), which may influence internal filter processing behavior. Documented i...
