How to fix?

Upgrade SLES:15.5 libsoup-lang to version 3.0.4-150400.3.55.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libsoup-lang package and not the libsoup-lang package as distributed by SLES. See How to fix? for SLES:15.5 relevant fixed versions and status.

A flaw was found in libsoup. The soup_uri_decode_data_uri() function incorrectly treated base64 data-URI payloads as NUL-terminated strings when calling g_base64_decode_inplace(). If the percent-decoded payload contained embedded NUL bytes, the decoded length could remain uninitialized and be used as the size of the returned GBytes. This can lead to an out-of-bounds read or application crash when processing a crafted data URI.
