Alpine: multiple php85 packages: security update to 8.5.12-r0

critical Tenable Cloud Security Plugin ID 476512

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- Attacker-provided inputs to bccomp() could lead to an out-of-bounds write with stack and heap corruption
in PHP versions from 8.4.* before 8.4.24 and from 8.5.* before 8.5.9. (CVE-2026-17544)

- The mysqlnd wire protocol parser reads fields out of server packets before checking that the packet still
holds enough bytes for them. A malicious or compromised MySQL server can send a truncated packet and make
the client read past the end of the packet buffer, which is undefined behaviour and can crash the process.
(CVE-2025-1218)

- The SOAP HTTP client guards its response buffer growth with a check that relies on signed integer
overflow, which is undefined behaviour and is not guaranteed to trigger. When the check is optimised away,
a malicious SOAP server can make the client allocate a buffer far smaller than the data it then writes
into it, producing a heap buffer overflow. (CVE-2025-14181)

- phar_tar_number() parses the octal size field of a TAR header into a uint32_t with no overflow check. The
field is 11 octal digits wide and holds values up to 0x1FFFFFFFF, so a size above 0xFFFFFFFF silently
wraps. The parser then skips the wrong number of data blocks and interprets attacker-controlled file
content as the next TAR header, which lets a crafted archive inject entries that PharData reports and
extracts as if they were genuine. (CVE-2026-6103)

- Circular symbolic links in phar archives could lead to unbounded recursion, exhausting the C stack and
crashing the PHP process, in PHP versions from 8.2.* before 8.2.33, from 8.3.* before 8.3.33, from 8.4.*
before 8.4.24, and from 8.5.* before 8.5.9. (CVE-2026-7260)
