libfreerdp/codec/region.c in FreeRDP through 1.1.x and 2.x through 2.0.0-rc4 has memory leaks because a supplied realloc pointer (i.e., the first argument to realloc) is also used for a realloc return value.

According to the versions of the freerdp packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - An issue was discovered in FreeRDP before 2.1.1. An     out-of-bounds (OOB) read vulnerability has been     detected in ntlm_read_ChallengeMessage in     winpr/libwinpr/sspi/NTLM/     ntlm_message.c.(CVE-2020-13396)

  - libfreerdp/codec/region.c in FreeRDP through 1.1.x and     2.x through 2.0.0-rc4 has memory leaks because a     supplied realloc pointer (i.e., the first argument to     realloc) is also used for a realloc return     value.(CVE-2019-17177)
