Lifecycle Timeline
1DescriptionNVD
In radare2 through 3.5.1, the rcc_context function of libr/egg/egg_lang.c mishandles changing context. This allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact (invalid memory access in r_egg_lang_parsechar; invalid free in rcc_pusharg).
AnalysisAI
In radare2 through 3.5.1, the rcc_context function of libr/egg/egg_lang.c mishandles changing context. Rated high severity (CVSS 7.8), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Technical ContextAI
This vulnerability is classified as Use After Free (CWE-416), which allows attackers to access freed memory to execute arbitrary code or crash the application. In radare2 through 3.5.1, the rcc_context function of libr/egg/egg_lang.c mishandles changing context. This allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact (invalid memory access in r_egg_lang_parsechar; invalid free in rcc_pusharg). Affected products include: Radare Radare2, Fedoraproject Fedora. Version information: through 3.5.1.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Use smart pointers or garbage-collected languages. Set pointers to NULL after freeing. Enable memory sanitizers.
