Description
This security bulletin contains information about 1 vulnerability.
1) Resource management errors (CVE-ID: CVE-2017-18075)
CWE-ID: CWE-399 - Resource Management Errors
CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a local attacker to cause DoS condition on the target system.
The weakness exists in crypto/pcrypt.c due to mishandling freeing instances. A local attacker can gain access to the AF_ALG-based AEAD interface (CONFIG_CRYPTO_USER_API_AEAD) and pcrypt (CONFIG_CRYPTO_PCRYPT), execute a crafted sequence of system calls and cause the service to crash (kfree of an incorrect pointer).
