Description

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

- Issue summary: A specially crafted PKCS#7 or S/MIME signed message could trigger a use-after-free during
PKCS#7 signature verification. Impact summary: A use-after-free may result in process crashes, heap
corruption, or potentially remote code execution. When processing a PKCS#7 or S/MIME signed message, if
the SignedData digestAlgorithms field is present as an empty ASN.1 SET, OpenSSL may incorrectly free a
caller-owned BIO during PKCS7_verify(). A subsequent use of the BIO by the calling application results in
a use-after-free condition. In the common case this occurs when the application later calls BIO_free() on
the BIO originally passed to PKCS7_verify(). Depending on allocator behavior and application-specific BIO
usage patterns, this may result in a crash or other memory corruption. In some application contexts this
may potentially be exploitable for remote code execution. Applications that process PKCS#7 or S/MIME
signed messages using OpenSSL PKCS#7 APIs may be affected. Applications using the CMS APIs for this
processing are not affected. The FIPS modules in 4.0, 3.6, 3.5, 3.4, and 3.0 are not affected by this
issue, as the affected code is outside the OpenSSL FIPS module boundary. (CVE-2026-45447)

Solution

Update the openssl-1.0.1g library and its related packages to version 1.0.1g+e1 or later.
