Echo: openssl: security update to 3.5.4-1~deb13u2

high Tenable Cloud Security Plugin ID 459332

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Issue summary: Calling PKCS12_get_friendlyname() function on a maliciously crafted PKCS#12 file with a
 BMPString (UTF-16BE) friendly name containing non-ASCII BMP code point can trigger a one byte write before
 the allocated buffer. Impact summary: The out-of-bounds write can cause a memory corruption which can have
 various consequences including a Denial of Service. The OPENSSL_uni2utf8() function performs a two-pass
 conversion of a PKCS#12 BMPString (UTF-16BE) to UTF-8. In the second pass, when emitting UTF-8 bytes, the
 helper function bmp_to_utf8() incorrectly forwards the remaining UTF-16 source byte count as the
 destination buffer capacity to UTF8_putc(). For BMP code points above U+07FF, UTF-8 requires three bytes,
 but the forwarded capacity can be just two bytes. UTF8_putc() then returns -1, and this negative value is
 added to the output length without validation, causing the length to become negative. The subsequent
 trailing NUL byte is then written at a negative offset, causing write outside of heap allocated buffer.
 The vulnerability is reachable via the public PKCS12_get_friendlyname() API when parsing attacker-
 controlled PKCS#12 files. While PKCS12_parse() uses a different code path that avoids this issue,
 PKCS12_get_friendlyname() directly invokes the vulnerable function. Exploitation requires an attacker to
 provide a malicious PKCS#12 file to be parsed by the application and the attacker can just trigger a one
 zero byte write before the allocated buffer. For that reason the issue was assessed as Low severity
 according to our Security Policy. The FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by this
 issue, as the PKCS#12 implementation is outside the OpenSSL FIPS module boundary. OpenSSL 3.6, 3.5, 3.4,
 3.3, 3.0 and 1.1.1 are vulnerable to this issue. OpenSSL 1.0.2 is not affected by this issue.
 (CVE-2025-69419)
